Suppose x has a distribution with μ = 24 and σ = 11.
1. If random samples of size n = 16 are selected, can we say anything about the x distribution of sample means?
2. If the original x distribution is normal, can we say anything about the x distribution of random samples of size 16?
3. Find P(20 ≤ x ≤ 25). (Round your answer to four decimal places.)
