Suppose a random sample of n measurements is selected from a population with mean m = 225 and variance s2

= 225. For each of the following values of n, give the LO6 mean and standard deviation of the sampling distribution of the sample mean x.

a. n = 9

b. n = 49

c. n = 225

d. n = 500

e. n = 1,000

f. n = 2,500
