The given scenario presents an auditor who wanted to test credit approval controls on 10,000 sales invoices with a maximum allowable proportion of invoices lacking approval of 7%.

To calculate the allowance for sampling risk, we need to first calculate the sample estimate of the population proportion of invoices lacking approval. We can do this by dividing the number of invoices lacking approval in the sample (7) by the total sample size (200):

Sample proportion = 7/200 = 0.035

Achieved precision limit = Sample proportion + Margin of error

Margin of error = Achieved upper precision limit - Sample proportion = 0.08 - 0.035 = 0.045

Achieved precision limit = 0.035 + 0.045 = 0.08

Allowance for sampling risk = Achieved precision limit - Desired precision limit

The desired precision limit is the maximum allowable proportion of invoices lacking approval, which is 7%:

Desired precision limit = 0.07

Substituting these values into the formula, we get:

Allowance for sampling risk = 0.08 - 0.07 = 0.01

Therefore, the allowance for sampling risk is 0.01, which means that the auditor is willing to accept a 1% risk of assessing control risk too low.

The z statistic for the hypothesis test is in the critical region. Therefore, the researcher can reject the null hypothesis, and she can conclude that the alternative hypothesis is probably correct.

To determine whether the z statistic is in the critical region, we compare it with the critical z value. The critical z value for a two-tailed test with an alpha of .001 is ±3.29. Since the calculated z statistic of 4.16 is greater than the critical z value, it falls within the critical region.

When the z statistic falls within the critical region, we reject the null hypothesis and accept the alternative hypothesis. In this case, since the researcher can reject the null hypothesis, she can conclude that the alternative hypothesis is probably correct.

Therefore, based on the given z statistic of 4.16 and an alpha of .001, the researcher can reject the null hypothesis and conclude that the alternative hypothesis is probably correct.

a) To determine the proportion of eggs produced on the farm that would be classified as extra-large, we need to compare the weight of extra-large eggs (78 grams or more) to the total weight of all eggs produced (2:6 grams).

Let's assume the total weight of eggs produced on the farm is W grams. The proportion of extra-large eggs would be the weight of extra-large eggs divided by the total weight of eggs:

Proportion of extra-large eggs = (Weight of extra-large eggs) / (Total weight of eggs)

b) To calculate the probability that a carton has at least one egg classified as extra-large, we need to consider the probability of selecting all small eggs and subtract it from 1. Assuming all eggs have an equal chance of being selected, the probability can be calculated as:

Probability = 1 - (Probability of selecting all small eggs)

c) If a carton contains exactly five eggs that would be classified as extra-large, we need to consider the total number of ways to select five extra-large eggs from the pool of eggs, divided by the total number of ways to select 12 eggs (assuming eggs are packed in one dozen cartons).

Probability = (Number of ways to select five extra-large eggs) / (Total number of ways to select 12 eggs)

d) The probability that the farmer's child does not find an extra-large egg until the fourth random selection can be calculated by considering the probability of selecting small eggs in the first three selections and multiplying it by the probability of selecting a non-extra-large egg on the fourth selection.

Probability = (Probability of selecting a small egg) * (Probability of selecting a small egg) * (Probability of selecting a small egg) * (Probability of selecting a non-extra-large egg)

The area to the left of 1.96 for part a and the area to the right of 1.96 for part b. Remember to label the curve, x-axis, and shaded areas appropriately.

To find the indicated areas under the standard Normal curve, you can use technology such as a calculator, spreadsheet software, or an online tool like a z-score calculator.
a. To find the area to the left of 1.96, input the z-score (1.96) into the calculator. The result is approximately 0.975. This means that about 97.5% of the area under the curve is to the left of 1.96.
b. To find the area to the right of 1.96, subtract the area found in part a from the total area under the curve (1). So, 1 - 0.975 = 0.025. This means that about 2.5% of the area under the curve is to the right of 1.96.
In your sketch, draw a standard Normal curve and mark 1.96 on the x-axis. Shade the area to the left of 1.96 for part a and the area to the right of 1.96 for part b. Remember to label the curve, x-axis, and shaded areas appropriately.

The slope of the line when graphing x1 on the horizontal axis and x2 on the vertical axis is -3/4.

To determine the slope of the line when graphing x1 on the horizontal axis and x2 on the vertical axis, we need to rearrange the given equation in the slope-intercept form, y = mx + b, where m is the slope.

6x1 + 8x2 = 240

First, let's isolate x2: 8x2 = -6x1 + 240

Dividing both sides by 8: x2 = (-6/8)x1 + 30

Now we have the equation in the form y = mx + b, where x1 is represented as the independent variable on the horizontal axis (x) and x2 as the dependent variable on the vertical axis (y).

Comparing the equation to y = mx + b, we can see that the coefficient of x1, which is -6/8 or -3/4, represents the slope of the line.

Therefore, the slope of the line when graphing x1 on the horizontal axis and x2 on the vertical axis is -3/4.

Investment B would have the greatest amount.

When we look at the compound interest, we know that the compound interest is compound not only on the principal but also on the interest that accrues to the investment.

We know that in the first case;

A = P(1 + r/n)^nt

A = amount

P = Principal

r = rate

n = Number of times compounded

t = time

Then;

A = 3000(1 + 0.08/2)^2 *7

= $5195

A = 5000(1 + 0.036/3)^3 * 4

A = $5769

Evan can play 2 games of mini golf and 9 games of kart track.

Given that Evan's mom gave him 11 tickets and left in game zone for 3 hours,

He can spend 1 ticket on one game, and he spend 10 minutes in kart track and a game of mini golf lasts 45 minutes.

We need to find how many games he played of both the games,

So, let he played x games of kart track and y games of mini golf,

So,

x + y = 11

x = 11 - y.............(i)

10x + 45y = 180...........(ii) [ ∵ 3 hours = 180 minutes]

Use the equation i in ii,

So,

10(11-y) + 45y = 180

110 - 10y + 45y = 180

35y = 70

y = 2

Put y = 2 in equation 1,

x = 11-2

x = 9

Hence he played 2 games of mini golf and 9 games of kart track.

Based on the given informations, the change in y as t changes from 1 to 6 is approximately 3.870. Therefore the correct option is (A).

To find the change in y as t changes from 1 to 6, we need to integrate the given function with respect to t over the interval [1, 6] and then find the difference between the values of the integral at the two endpoints.

∫₁⁶ 6e\(.^{(-0.08(t-5)^2)}\)  dt

We can use the substitution u = t - 5 to simplify the integral:

∫₋₄¹ 6e\(.^{(-0.08u^2)}\)  du

Unfortunately, there is no closed-form solution for this integral. We can use numerical integration methods, such as Simpson's rule or the trapezoidal rule, to approximate the integral. Using Simpson's rule with a step size of 1, we get:

∫₋₄¹ 6e\(.^{(-0.08u^2)}\) du ≈ 3.870

Therefore, the change in y as t changes from 1 to 6 is approximately 3.870, which corresponds to option (A).
