Repeat Exercise 6.7, but select each sample with replacement; that is, replace each slip of paper and reshuffle before the next one is drawn.

Data From Exercise 6.7

6.7 Take 30 slips of paper and label five each -4 and

4, four each-3 and 3, three each-2 and 2, and two each

6.7 Take 30 slips of paper and label five each -4 and 4, four each-3 and 3, three each-2 and 2, and two each -1,0 and 1. (a) If each slip of paper has the same probability of being drawn, find the probability of getting -4, -3, -2, -1, 0, 1, 2, 3, 4 and find the mean and the variance of this distribution. (b) Draw 50 samples of size 10 from this population, each sample being drawn without replacement, and calculate their means.
