Suggest the set of odd single-digit integers {1, 3, 5, 7, 9}.
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. Construct the sampling distribution of sample means for samples of size 2 selected from this set.
c. Construct the sampling distributions of sample ranges for samples of size 2.
