Suppose x has a distribution with = 15 and = 14

a. If a random sample of size n = 49 is drawn, what is the standard error of the sampling distribution?

b. Find P (15 < < 17) for a random sample of size n = 49.

c. If a random sample of size n = 64 is drawn, what is the standard error of the sampling distribution?

d. Find P (15 < < 17) for a random sample of size n = 64.

e. Compare the probabilities found in b and d. Why is one larger than the other one?
