Consider the set of even single-digit integers {0, 2, 4, 6, 8}.
a. Make a list of all samples of size 2 that can be drawn from this set of integers. (Sample with replacement; that is, the first number is drawn, observed, and then replaced [returned to the sample set] before the next drawing.)
b. Develop the sampling distribution of sample means for samples of size 2 selected from this set.
c. Develop the sampling distributions of sample ranges for samples of size 2.
