The cumulative probability of obtaining a sample result will be approximately 0.0001

We have to apply Formula of Binomial Distribution:

P(X ≤ 168) = ΣP(X = i) for i = 0, 1, 2, .., 168, here in a sample of size n, P(X = i) is the probability of getting exactly i success

We assume that company's claim is true, 0.8 is the probability of success for each trial

P(X = i) = (200 choose i)×\(0.8^{i}\) ×\(0.2^{200- i}\)

By using this, we can easily find that cumulative probability is 0.0001

So, the probability is very low, this means that company's claim of an 80% success rate can be incorrect

So, further analysis may be needed to draw some conclusions and results

The approximate probability of being dealt a royal flush on the first deal is approximately 0.00000154, or 1 in 649,740.

What is probability?

Probability is a mathematical concept that measures the likelihood or chance of an event occurring. It quantifies the uncertainty associated with the outcome of a particular event or experiment. Probability is expressed as a number between 0 and 1, where 0 indicates impossibility (the event will not happen) and 1 represents certainty (the event will definitely happen).

What is a binomial coefficient?

A binomial coefficient, often denoted as "n choose k" or "C(n, k)," is a mathematical term that represents the number of ways to choose k items from a set of n distinct items, without regard to their order. It is a fundamental concept in combinatorics.

What is factorial?

Factorial is a mathematical function denoted by an exclamation mark (!) following a non-negative integer. It represents the product of all positive integers less than or equal to that integer.

To calculate the number of possible five-card poker hands, we can use the concept of combinations. The number of ways to choose 5 cards out of a deck of 52 cards is given by the binomial coefficient "52 choose 5," which can be calculated as:

C(52, 5) = 52! / (5! * (52 - 5)!)

Now, let's calculate the number of possible royal flush hands. Since there are 4 suits, and each suit can form a royal flush, we multiply the number of suits by the number of ways to arrange the five cards within each suit. So, the total number of possible royal flush hands is:

4 * 1 = 4

The probability of being dealt a royal flush on the first deal is the number of favourable outcomes (royal flush hands) divided by the number of possible outcomes (all possible five-card hands). Therefore, the probability is:

P(royal flush) = 4 / C(52, 5)

Calculating this probability:

P(royal flush) = 4 / (52! / (5! * (52 - 5)!))

To simplify the calculation, we can use the fact that the factorial of a number can be expressed as the product of all the integers from 1 up to that number. For example:

n! = n * (n - 1) * (n - 2) * ... * 3 * 2 * 1

Using this knowledge, we can simplify the expression for C(52, 5) as follows:

C(52, 5) = 52! / (5! * (52 - 5)!)

= (52 * 51 * 50 * 49 * 48) / (5 * 4 * 3 * 2 * 1)

Simplifying further, we have:

C(52, 5) = 2,598,960

Now, let's substitute this value back into the probability calculation:

P(royal flush) = 4 / C(52, 5)

= 4 / 2,598,960

Calculating this probability:

P(royal flush) ≈ 0.00000154

Hence, the approximate probability of being dealt a royal flush on the first deal is approximately 0.00000154, or 1 in 649,740.

The regression line equation for predicting average weekly sales for stores with 13 feet of shelf space is:

\(Y = -0.63825 + 0.1938 * 13\)

What is linear regression?

Linear regression is a statistical analysis technique used to model the relationship between a dependent variable (in this case, weekly sales) and one or more independent variables (in this case, store shelf space). It assumes a linear relationship between the variables and aims to find the best-fitting line that represents this relationship. The equation of the regression line allows for predicting the value of the dependent variable based on the given independent variable(s)

To predict the average weekly sales for stores with 13 feet of shelf space, we can use linear regression analysis. Let's calculate the regression line equation using the given data:

Store Shelf Space (X) | Weekly Sales (Y)

\(1 10 2.02 10 2.63 10 1.84 15 2.35 15 2.86 15 3.07 20 2.78 20 3.19 20 3.210 25 3.011 25 3.312 25 3.5\)

Step 1: Calculate the mean of X and Y:

Mean\((X) = (10 + 10 + 10 + 15 + 15 + 15 + 20 + 20 + 20 + 25 + 25 + 25) / 12 = 17.5\)

Mean\((Y) = (2.0 + 2.6 + 1.8 + 2.3 + 2.8 + 3.0 + 2.7 + 3.1 + 3.2 + 3.0 + 3.3 + 3.5) / 12 = 2.75\)

Step 2: Calculate the deviations from the means:

X deviations: \(10 - 17.5, 10 - 17.5, 10 - 17.5, 15 - 17.5, 15 - 17.5, 15 - 17.5, 20 - 17.5, 20 - 17.5, 20 - 17.5, 25 - 17.5, 25 - 17.5, 25 - 17.5\)

Y deviations: \(2.0 - 2.75, 2.6 - 2.75, 1.8 - 2.75, 2.3 - 2.75, 2.8 - 2.75, 3.0 - 2.75, 2.7 - 2.75, 3.1 - 2.75, 3.2 - 2.75, 3.0 - 2.75, 3.3 - 2.75, 3.5 - 2.75\)

Step 3: Calculate the product of the deviations:

(X deviations * Y deviations):

\(-7.5 * -0.75 = 5.625-7.5 * 0.85 = -6.375-7.5 * -0.95 = 7.125-2.5 * -0.45 = 1.125-2.5 * 0.05 = -0.125-2.5 * 0.25 = -0.6252.5 * -0.05 = -0.1252.5 * 0.35 = 0.8752.5 * 0.45 = 1.1257.5 * 0.25 = 1.8757.5 * 0.55 = 4.1257.5 * 0.75 = 5.625\)

Step 4: Calculate the sum of squared X deviations:

X deviations squared:

\((-7.5)^2 = 56.25(-7.5)^2 = 56.25\)

Step 5: Calculate the sum of the product of X deviations and Y deviations:

Sum of (X deviations * Y deviations)\(= 5.625 + (-6.375) + 7.125 + 1.125 + (-0.125) + (-0.625) + (-0.125) + 0.875 + 1.125 + 1.875 + 4.125 + 5.625 = 21.75\)

Step 6: Calculate the slope (b):

b = Sum of (X deviations * Y deviations) / Sum of X deviations squared = \(21.75 / (56.25 + 56.25) = 21.75 / 112.5 = 0.1938\)

Step 7: Calculate the intercept (a):

a = Mean(Y) - b * Mean\((X) = 2.75 - 0.1938 * 17.5 = 2.75 - 3.38825 = -0.63825\)

Step 8: Write the regression line equation:

Y = a + bX

Y = -0.63825 + 0.1938X

Therefore, the regression line equation for predicting average weekly sales for stores with 13 feet of shelf space is:

\(Y = -0.63825 + 0.1938 * 13\)

In order to completely delta hedge 480 shares of ABC company with an option delta of 0.6, you would need 3 call options.

To completely delta hedge your holdings of 480 shares of ABC company, you would need to calculate the number of call options required based on the delta of the option. The delta represents the change in the option price relative to the change in the underlying stock price. In this case, since the delta is given as 0.6, it means that for every $1 increase in the stock price, the option price will increase by $0.6.

To calculate the number of call options needed for delta hedging, you can use the following formula:

Number of call options = (Delta * Number of shares) / 100

Plugging in the given values, we have:

Number of call options = (0.6 * 480) / 100

Number of call options = 2.88

Since you cannot have a fractional number of options, you would need to round up to the nearest whole number. Therefore, you would need 3 call options to hedge your 480 shares of ABC company.

In summary, to completely delta hedge 480 shares of ABC company with an option delta of 0.6, you would need to acquire 3 call options.

The sample mean of the weights at the birth of the randomly chosen infants is 7.6 pounds.

Given: The sample of seven infants was selected randomly and the weights are: {9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6} (in pounds)

What is a sample?

A sample can be defined as a part of something big or a whole. It can be some of the elements from a given set of elements.

For example: Let us consider the set of natural numbers. The set of natural numbers has an infinite number of elements in it. We choose some numbers from the set, say {2, 7, 9, 10, 99, 200, 234}. These chosen numbers are known as samples from the set of natural numbers.

What is the sample mean?

The sample mean is the average value of the samples or it is the mean of all the elements which exist in the given sample.

The sample mean is denoted by x⁻ which is pronounced as x bar.

The formula to calculate sample mean (x⁻) is:

Sample Mean (x⁻) = Summation of all the elements in the sample / Total number of elements in the sample.

x⁻ = ∑xₙ / n

where,

∑xₙ = Summation of all the elements in the sample

n = Total number of elements in the sample

x⁻ = Sample mean

Now let's solve the given question:

The given sample is {9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6}

The summation of the elements in the sample is:

∑xₙ = 9.0 + 7.3 + 6.0 + 8.8 + 6.8 + 8.4 + 6.6

∑xₙ = 52.9

The total number of elements in the sample is:

n = 7

Therefore, the sample mean (x⁻) is:

x⁻ = ∑xₙ / n

x⁻ = 52.9 / 7

x⁻ = 7.5571 ≈ 7.6

Hence the sample mean of the weights at the birth of the randomly chosen infants is 7.6 pounds.

The graph that represents the geometric sequence f(x) = (1) ∙ (2)^(x-1) is graph C.

A geometric sequence is a sequence of numbers where each term is equal to the previous term multiplied by a constant value, called the common ratio. In this case, the common ratio is 2. This means that the first term of the sequence is 1, the second term is 1 * 2 = 2, the third term is 2 * 2 = 4, and so on.

The graph of a geometric sequence is a curve that gets closer and closer to the y-axis as x gets larger. This is because the terms of the sequence get smaller and smaller as x gets larger. In the case of the sequence f(x) = (1) ∙ (2)^(x-1), the terms of the sequence get smaller and smaller as x gets larger because the common ratio is 2, which is greater than 1.

Graph C is the only graph that meets all of these criteria. The curve in graph C gets closer and closer to the y-axis as x gets larger. This is because the terms of the sequence f(x) = (1) ∙ (2)^(x-1) get smaller and smaller as x gets larger. Therefore, graph C is the graph that represents the geometric sequence f(x) = (1) ∙ (2)^(x-1).
