Suppose x has a distribution with μ = 32 and σ = 17. (a) If random samples of size n = 16 are selected, can we say anything about the x distribution of sample means? No, the sample size is too small. Yes, the x distribution is normal with mean μ x = 32 and σ x = 17. Yes, the x distribution is normal with mean μ x = 32 and σ x = 1.1. Yes, the x distribution is normal with mean μ x = 32 and σ x = 4.25. Correct: Your answer is correct. (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 = 32 and σ x = 17. No, the sample size is too small. Yes, the x distribution is normal with mean μ x = 32 and σ x = 1.1. Yes, the x distribution is normal with mean μ x = 32 and σ x = 4.25. Correct: Your answer is correct. Find P(28 ≤ x ≤ 33). (Round your answer to four decimal places.)
