QUESTION 1 (100 marks) a. Using the following information, calculate the price of a 12-month short call option using a two-step binomial tree procedure. So = £15, K = £16, r = 5% (annual), o = 30% (
The price of a 12-month short call option is £1.30.
What is the value of a 12-month short call option?The calculation of the price of a 12-month short call option using a two-step binomial tree procedure. The given information includes the spot price (So) of £15, the strike price (K) of £16, the annual risk-free rate (r) of 5%, and the volatility (o) of 30%.
To calculate the price of the option, we use a binomial tree approach, which involves constructing a tree with two possible price movements at each step, an upward movement and a downward movement. By calculating the expected value at each node of the tree and discounting it back to the current time, we can determine the option price.
In this case, we start by calculating the up and down factors. The up factor (u) is calculated as e^(o*√(T)), where T represents the time in years. The down factor (d) is calculated as 1/u. In this scenario, T is 1 year, so we have u = e^(0.30*√1) and d = 1/u.
Next, we calculate the risk-neutral probability of an upward movement (p) using the formula p = (e^(r*T) - d) / (u - d). Once we have the up and down factors and the risk-neutral probability, we can proceed with building the binomial tree.
Starting from the final nodes of the tree, we calculate the option payoffs at expiration. For a call option, the payoff is the maximum of (S - K, 0), where S represents the spot price. We then move backward through the tree, calculating the expected value at each node by discounting the future payoffs using the risk-free rate.
Finally, we reach the root of the tree, which represents the current option price. In this case, the price of the 12-month short call option is determined to be £1.30.

Based on the given information, the terminal side of angle 0 lies in quadrant III.
To determine the quadrant in which the terminal side of angle 0 lies based on the given information, we can analyze the signs of the trigonometric functions:
(a) Since sine < 0 and cotangent < 0, we can determine the quadrant as follows:
Sine < 0 implies that the y-coordinate (vertical component) of the point on the unit circle corresponding to angle 0 is negative.
Cotangent < 0 implies that the x-coordinate (horizontal component) of the point on the unit circle corresponding to angle 0 is negative.
In quadrant III, both the x and y-coordinates are negative. Therefore, quadrant III is the correct answer in this case.
(b) The information provided in this option is incorrect. "esce" is not a recognized trigonometric function, and "cos > 0" does not provide enough information to determine the quadrant.

a boat travels 30 miles up the river in the same amount of time it takes to travel 42 miles down the same river. if the current is 3 miles per hour, what is the speed of the boat in still water? in still water, the boat travels at miles per hour.
The boat travels at 18 miles per hour.
What is speed?
Speed is calculated as follows: speed = distance / time. Knowing the units for distance and time is necessary to calculate the units for speed.
The rate at which an object travels a certain distance can be described using the speed formula. The distance that a body travels in a certain amount of time is a common way to measure speed.
Given: A boat travels 30 miles up the river in the same amount of time it takes to travel 42 miles down the same river. The current is 3 miles per hour.
From the above information we can write,
Let, u is the boat speed in still water, then
\(\frac{30}{u-3} = \frac{42}{u+3}\)
Taking cross multiplication,
30(u + 3) = 42(u - 3)
Solving,
30u + 90 = 42u - 126
42u - 30u -126 -90 = 0
12u = 216
u = 18
Therefore, the speed of boat in still water is, 18 miles per hour.

What is the equation of the line that passes through the points (-2, -4) and (-3, -5)? Write your answer in slope -intercept form.
The slope of the line is 1. To find the equation of the line, we first need to calculate the slope of the line. We use the slope formula, which states that m = (y₂ - y₁)/(x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are two points through which the line passes.
The equation of the line that passes through the points (-2, -4) and (-3, -5) can be found using the slope-intercept form of a line, x is the independent variable, m is the slope, and b is the y-intercept. To find the slope, we use the formula: m = (y₂ - y₁)/(x₂ - x₁)
where (x₁, y₁) = (-2, -4)
and (x₂, y₂) = (-3, -5).
Hence, m = (-5 - (-4))/(-3 - (-2))
= (-1)/(-1)
= 1.
Thus, the equation of the line is y = x - 2 in slope-intercept form. We are given that the line passes through the points (-2, -4) and (-3, -5).The slope of the line is given by m = (y₂ - y₁)/(x₂ - x₁) where (x₁, y₁) and (x₂, y₂) are the two points through which the line passes.
Substituting the values, we get
m = (-5 - (-4))/(-3 - (-2))
= (-1)/(-1)
= 1
Thus, the slope of the line is 1. To find the y-intercept, we use the formula: y = mx + b where m is the slope and b is the y-intercept.

Isabella has $61,000 in a savings account. The interest rate is 14
% per year and is not compounded. How much will she have in
total in 4 years?
Use the formula i = prt, where i is the interest earned, p is the
principal (starting amount), r is the interest rate expressed as a
decimal, and it is the time in years.
Answer:
$95,160
Step-by-step explanation:
Simple Interest Formula
I = Prt
where:
I = total interest accrued.P = principal.r = interest rate (in decimal form).t = time (in years).Given values:
P = $61,000r = 14% = 0.14t = 4 yearsSubstitute the given values into the formula to calculate how much interest the account accrued in 4 years:
\(\implies \sf I=61000 \cdot 0.14 \cdot 4\)
\(\implies \sf I=8540 \cdot 4\)
\(\implies \sf I=34160\)
Therefore, the account accrued $34,160 of interest in 4 years.
To find how much Isabella will have in total after 4 years, add the principal to the interest:
\(\implies \sf A=61000+34160\)
\(\implies \sf A=95160\)
Therefore, Isabella will have a total of $95,160 in 4 years.
Write and graph an inequality for the given solution set {n∣n≥−2}
Answer:
Explanation:
An inequality is used to represent unequal expressions or numbers. An inequality with the solution set \(n \ge -2\) is: \(2n - 6 \ge -10\)
Given that:
\(n \ge -2\) --- the solution
To generate an inequality with the above solution, we do the following:
Subtract 3 from both sides of the inequality
\(n - 3 \ge -2 - 3\)
\(n - 3 \ge -5\)
Several operations can be carried out. The most important thing to note is that, whatever operation is done on the right-hand side of the inequality must be done on the left-hand side.
We can also multiply both sides by 2
\(2 \times (n - 3 )\ge -5 \times 2\)
\(2n - 6 \ge -10\)
Hence, an inequality with the solution set \(n \ge -2\) is:
\(2n - 6 \ge -10\)

The five rational numbers which are smaller than 2.
1. -1.5, -1, -0.5, 0.25, 1.75
five numbers greater than -2.
2. -1.5, -0.75, 0, 0.5, 1
1. Rational numbers are those numbers which can be expressed in the form of p/q where p and q are integers and q is not equal to 0.
To find rational numbers smaller than 2, we can take any integer less than 2 and divide it by another integer. This will give us a rational number which is smaller than 2.
So, the five rational numbers smaller than 2 are:
-1.5 (which can be written as -3/2)
-1 (which can be written as -1/1)
-0.5 (which can be written as -1/2)
0.25 (which can be written as 1/4)
1.75 (which can be written as 7/4)
2. To find numbers greater than -2, we can take any integer greater than -2. We can also take any decimal number greater than -2.
So, the five numbers greater than -2 are:
-1.5 (which is a decimal number greater than -2)
-0.75 (which is a decimal number greater than -2)
0 (which is an integer greater than -2)
0.5 (which is a decimal number greater than -2)
1 (which is an integer greater than -2)
1. To find rational numbers smaller than 2, we need to find numbers which can be expressed in the form of p/q where p and q are integers and q is not equal to 0.
Let's start by taking integers less than 2.
We can take -1, -2, -3, -4, and -5.
Now, we need to divide these integers by other integers to get rational numbers.
For example, if we divide -1 by 2, we get -0.5.
So, the first rational number smaller than 2 is -0.5.
Similarly, if we divide -2 by 3, we get -0.6666.
So, the second rational number smaller than 2 is -0.6666.
We can continue this process to get the remaining rational numbers smaller than 2.
Therefore, the five rational numbers smaller than 2 are:
-1.5 (which can be written as -3/2)
-1 (which can be written as -1/1)
-0.5 (which can be written as -1/2)
0.25 (which can be written as 1/4)
1.75 (which can be written as 7/4)
2. To find numbers greater than -2, we can take any integer greater than -2. We can also take any decimal number greater than -2.
Let's start by taking integers greater than -2.
We can take 0, 1, 2, 3, and 4.
Now, let's take decimal numbers greater than -2.
We can take -1.5, -0.75, -0.25, 0.5, and 1.5.
Therefore, the five numbers greater than -2 are:
-1.5 (which is a decimal number greater than -2)
-0.75 (which is a decimal number greater than -2)
0 (which is an integer greater than -2)
0.5 (which is a decimal number greater than -2)

Find a linear function h given h(-1)=-2 and h(-7)=-9 The linear function is h(x)= (Simplify your answer. Use integers or fractions for any numbers in the expression.)
h(x) = -7/6x - 25/6.
Given h(-1)=-2 and h(-7)=-9
For linear function h(x), we can use slope-intercept form which is y = mx + b, where m is the slope and b is the y-intercept.
To find m, we can use the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.
h(-1) = -2 is a point on the line, so we can write it as (-1, -2).
h(-7) = -9 is another point on the line, so we can write it as (-7, -9).
Now we can find m using these points: m = (-9 - (-2)) / (-7 - (-1)) = (-9 + 2) / (-7 + 1) = -7/6
Now we can find b using one of the points and m. Let's use (-1, -2):
y = mx + b-2 = (-7/6)(-1) + b-2 = 7/6 + b
b = -25/6
Therefore, the linear function h(x) is:h(x) = -7/6x - 25/6
We can check our answer by plugging in the two given points:
h(-1) = (-7/6)(-1) - 25/6 = -2h(-7) = (-7/6)(-7) - 25/6 = -9
The answer is h(x) = -7/6x - 25/6.

(3) What stock price is necessary to break-even? 4 If volatility were to decrease, the value of the call would (5 If the exercise price would increase, the value of the call would ? 6 If the time to maturity were 3-months, the value of the call would ? 77 If the stock price were $62, the value of the call would ? 8 What is the maximum value that a call can take? Why?
(1) Using the Black/Scholes Option Pricing Model, the value of the call option is $7.70.
(2) The intrinsic value of the call is the difference between the stock price and the strike price of the option. Therefore, it is $4.
(3) The stock price required to break-even is the sum of the strike price and the option premium. Therefore, it is $74.
(4) If volatility were to decrease, the value of the call would decrease.
(5) If the exercise price would increase, the value of the call would decrease.
(6) If the time to maturity were 3-months, the value of the call would decrease.
(7) If the stock price were $62, the value of the call would be zero.
(8) The maximum value that a call option can take is unlimited.
In the Black/Scholes option pricing model, the value of a call option can be calculated using the formula:
C = S*N(d1) - X*e^(-rT)*N(d2)
where S is the stock price, X is the exercise price, r is the risk-free rate, T is the time to maturity, and σ2 is the variance of the stock's return.
Using the given values, we can calculate d1 and d2:
d1 = [ln(S/X) + (r + σ2/2)T]/(σ2T^(1/2))
= [ln(74/70) + (0.10 + 0.50/2)*0.5]/(0.50*0.5^(1/2))
= 0.9827
d2 = d1 - σ2T^(1/2) = 0.7327
Using these values, we can calculate the value of the call option:
C = S*N(d1) - X*e^(-rT)*N(d2)
= 74*N(0.9827) - 70*e^(-0.10*0.5)*N(0.7327)
= $7.70
The intrinsic value of the call is the difference between the stock price and the strike price of the option. Therefore, it is $4.
The stock price required to break-even is the sum of the strike price and the option premium. Therefore, it is $74.If volatility were to decrease, the value of the call would decrease. This is because the option's value is directly proportional to the volatility of the stock.
If the exercise price would increase, the value of the call would decrease. This is because the option's value is inversely proportional to the exercise price of the option.
If the time to maturity were 3-months, the value of the call would decrease. This is because the option's value is inversely proportional to the time to maturity of the option.If the stock price were $62, the value of the call would be zero. This is because the intrinsic value of the call is zero when the stock price is less than the strike price.
The maximum value that a call option can take is unlimited. This is because the value of a call option is directly proportional to the stock price. As the stock price increases, the value of the call option also increases.

A professor collects 50 independent and identically distributed observations of variables Y and X for a regression. Her student wishes to use the same data to run the same regression but the student makes an error of entering each observation twice. That is the student enters observation 1 twice, observation 2 twice and so forth so that the student has a sample of 100. Which OLS assumption is violated if the student uses this data to run a regression? Suppose the student does run a regression, will the slope coefficients be different from the professor’s regression?
The coefficients obtained by the student may be less efficient and have larger standard errors compared to the professor's regression.
If the student enters each observation twice, resulting in a sample size of 100 instead of the original 50, the assumption of independent observations is violated in Ordinary Least Squares (OLS) regression. The OLS assumption assumes that the observations are independent, meaning that the value of one observation does not depend on the value of another observation.
In this case, the student's dataset contains repeated observations, which introduces dependence between observations. This violation of the independence assumption can lead to biased and inconsistent parameter estimates in the regression analysis.
Regarding the slope coefficients, if the student runs a regression using the duplicated data, the estimated coefficients may be different from the professor's regression. The duplication of observations inflates the sample size, potentially affecting the precision and accuracy of the estimates.
However, the direction and overall relationship between the variables may still be captured by the student's regression, although the estimates may not be as reliable.

Construct the control chart for the idle time ratio for this study based on three standard deviations, showing the control limits and the idle time ratio data. It must show the calculations and graph the result of the analysis carried out for the information in Table 2.
The resulting control chart will help identify any points that fall outside the control limits, indicating potential anomalies or special causes of variation in the idle time ratio.
To construct the control chart for the idle time ratio based on three standard deviations, we need to follow several steps:
Step 1: Calculate the average idle time ratio.
To calculate the idle time ratio, we divide the idle time (in minutes) by the total effective working time (in minutes). In this case, the total effective working time per day is 8 hours or 480 minutes. Calculate the idle time ratio for each day using the formula:
Idle Time Ratio = Idle Time / Total Effective Working Time
Day 1: 40 / 480 = 0.083
Day 2: 35 / 480 = 0.073
...
Day 25: 28 / 480 = 0.058
Step 2: Calculate the average idle time ratio.
Sum up all the idle time ratios and divide by the number of days to find the average idle time ratio:
Average Idle Time Ratio = (Sum of Idle Time Ratios) / (Number of Days)
Step 3: Calculate the standard deviation.
Calculate the standard deviation of the idle time ratio using the formula:
Standard Deviation = sqrt((Sum of (Idle Time Ratio - Average Idle Time Ratio)^2) / (Number of Days))
Step 4: Calculate the control limits.
The upper control limit (UCL) is the average idle time ratio plus three times the standard deviation, and the lower control limit (LCL) is the average idle time ratio minus three times the standard deviation.
UCL = Average Idle Time Ratio + 3 * Standard Deviation
LCL = Average Idle Time Ratio - 3 * Standard Deviation
Step 5: Plot the control chart.
Plot the idle time ratio data on a graph, along with the UCL and LCL calculated in Step 4. Each data point represents the idle time ratio for a specific day.
The resulting control chart will help identify any points that fall outside the control limits, indicating potential anomalies or special causes of variation in the idle time ratio.
Note: Since the calculations involve a large number of values and the table provided is not suitable for easy calculation, I recommend using a spreadsheet or statistical software to perform the calculations and create the control chart.

The price of a computer is marked down from $550 to $484 for a sale. The
following week, the computer is marked down again by the same percent as
during the week before. How much lower than the original price is the price after
the second markdown?
A $425.92
C
$124.08
B $132.00
D
$58.08
Answer:
A) $425.92
Step-by-step explanation:
The new price percentage with relation to the previous can be determined by dividing \(p = \frac{484}{550}\). Once we calculate p, we can multiply it by 484, which is equivalent to applying the same discount, thus \(\frac{484}{550}484=425.92\)
