Question: Suppose that x has a distribution with μ = 72 and σ = 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).
