Suppose x has a distribution with = 69 and σ = 17. (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 = 69 and a = 4.25. No, the sample size is too small. Yes, the x distribution is normal with mean = 69 and ox= 1.1. Yes, the x distribution is normal with mean μ = 69 and 0 = 17. (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 x=69 and ox= 1.1. = 69 and 0= 4.25. Yes, the x distribution is normal with mean Yes, the x distribution is normal with mean No, the sample size is too small. = 69 and 0x = 17. Find P(65 ≤ x ≤ 70).
