Suppose x has a distribution with u = 85 and 6 = 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 = 85 and 0 , = 2.75. • No, the sample size is too small. Yes, the x distribution is normal with mean = 85 and x = 11. Yes, the x distribution is normal with mean...
