For the following situation, find the mean and standard deviation of the population. List all samples (with replacement) of the given size from that population and find the mean of each. Find the mean and standard deviation of the sampling distribution and compare them with the mean and standard deviation of the population. The scores of three students in a study group on a test are 90, 95, 97. Use a sample size of 3.

I've already done parts a and b of the problem. I need help with parts c and d.
a) The mean of the population is 94.
(Round to two decimal places as needed.)

b) The standard deviation of the population is 2.94.
(Round to two decimal places as needed.)

c) Identify all samples of size 3 with the correct accompanying means below.
(27 possible)

d) Find the mean and the standard deviation of the sampling distribution.
