Suppose x has a distribution with μ = 21 and σ = 11. (a) If random samples of size n = 16 are selected, can we say anything about the x distribution of sample means? Yes, the x distribution is normal with mean μ x = 21 and σ x = 11.Yes, the x distribution is normal with mean μ x = 21 and σ x = 2.75. No, the sample size is too small.Yes, the x distribution is normal with mean μ x = 21 and σ x = 0.7. (b) If the original x distribution is normal, can we say anything about the x distribution of random samples of size 16? Yes, the x distribution is normal with mean μ x = 21 and σ x = 2.75.Yes, the x distribution is normal with mean μ x = 21 and σ x = 0.7. Yes, the x distribution is normal with mean μ x = 21 and σ x = 11.No, the sample size is too small. Find P(17 ≤ x ≤ 22). (Round your answer to four decimal places.)
