Question: Suppose that has a distribution with μ = 72 and \(\sigma \) = 8.

(a) If random samples of size n = 16 are selected, can we say anything about the x distribution of sample means?

(b) If the original x distribution is normal, can we say anything about the x distribution of random samples of size 16? Find P(68 ≤ x ≤ 73).
