Exercise 7.9 Suppose that we take a random sample of size n from a population having a mean (m) and standard deviation (s). For each of the following cases find the mean, variance and standard deviation of the sampling distribution of the sample mean :

a.m = 500, s = 0.5 and n = 100

b.m = 10, s = 2 and n = 30
