# Question

Use the same population of {4, 5, 9} from Example 1 in Section 6-4. Assume that samples of size n = 2 are randomly selected without replacement.

a. Find µ and σ for the population.

b. After finding all samples of size n = 2 that can be obtained without replacement, find the population of all values of x by finding the mean of each sample of size n = 2.

c. Find the mean µx and standard deviation σx for the population of sample means found in part (b).

d. Verify that
