Suppose x has a distribution with = 17 and = 16. A button hyperlink to the SALT program that reads: Use SALT. (a) If a random sample of size n = 47 is drawn, find x, x and P(17 ≤ x ≤ 19). (Round x to two decimal places and the probability to four decimal places.) x = x = P(17 ≤ x ≤ 19) = (b) If a random sample of size n = 72 is drawn, find x, x and P(17 ≤ x ≤ 19). (Round x to two decimal places and the probability to four decimal places.) x = x = P(17 ≤ x ≤ 19) = (c) Why should you expect the probability of part (b) to be higher than that of part (a)? (Hint: Consider the standard deviations in parts (a) and (b).) The standard deviation of part (b) is ---Select--- part (a) because of the ---Select--- sample size. Therefore, the distribution about x is
