Suppose Jack and Diane are each attempting to use a simulation to describe the sampling distribution from a population that is skewed right with mean 50 and standard deviation 5. Jack obtains1000 random samples of size n = 4 from the population, finds the mean of the means, and determines the standard deviation of the means. Diane does the same simulation, but obtains 1000 randomsamples of size n = 35 from the population. Complete parts (a) through (c).(a) Describe the shape you expect for Jack's distribution of sample means. Describe the shape you expect for Diane's distribution of sample means. Choose the correct answer below.A. Jack's distribution and Diane's distribution are expected to be approximately normal. However, Jack's will have the smaller standard deviation of the sample mean.B. Diane's distribution is expected to be skewed right, but less skewed than the original distribution. Jack's distribution is expected to be approximately normal.C. Jack's distribution is expected to be skewed right, but less skewed than the original distribution. Diane's distribution is expected to be approximately normal.D. Jack's distribution and Diane's distribution are expected to be approximately normal. However, Jack's will have the greater standard deviation of the sample mean.(b) What do you expect the mean of Jack's distribution to be? What do you expect the mean of Diane's distribution to be?Jack's distribution is expected to have a mean of . Diane's distribution is expected to have a mean of(Type integers or decimals rounded to two decimal places as needed.)(c) What do you expect the standard deviation of Jack's distribution to be? What do you expect the standard deviation of Diane's distribution to be?Jack's distribution is expected to have a standard deviation of . Diane's distribution is expected to have a standard deviation of(Type integers or decimals rounded to two decimal places as needed.)

3D1 3 4 5 6 8 9 10 Sweet Rush is an ice cream shop chain that has locations all across the nation, Customers at Sweet Rush have the option of ordering 1, 2, or 3 scoops of ice cream in their cone. The mean number of scoops ordered is u = 1.40, with a standard deviation of o =0.85. Suppose that we will take a random sample of n= 10 ice cream cone orders and record the number of scoops for each. Let x represent the sample mean of the number of scoops for the 10 ice cream cone orders. Consider the sampling distribution of the sample mean x. Complete the following. Do not round any intermediate computations. Write your answers with two decimal places, rounding if needed. (a) Find u- (the mean of the sampling distribution of the sample mean). (b) Find G- (the standard deviation of the sampling distribution of the sample mean).

Suppose that you want to perform a hypothesis test for a population mean. Assume that the population standard deviation is unknown and that the sample size is relatively small. In each exercise, we have given the distribution shape of the variable under consideration. Decide whether you would use the t-test, the Wilcoxon signed-rank test, or neither. Explain your answers.
