ACTIVITY : Suppose that we will take a random sample of size n from a population having mean u and standard deviation o. For each of the following situations, find the mean of the sampling distribution of the sample mean x: a u = 10, 0 = 2, n = 25 bu = 500, or= .5, n = 100 C u=3, 0= 1, n=4 d u = 100, or = 1, n = 1,600
