with ME = 400 and X distributed A random sample with size, n = 30, is obtained from a normal distribution population with = 13 and 0 = 7. X ~ N (M = 13, 0 = 7) MI = M = 13 30 . 278 * 13 a) What are the mean and the standard deviation for the sampling distribution of sample mean. dismbut on 18 since 17/ 30 10 0 K What is the shape of the sampling distribution?
