Suppose x has a distribution with ? = 14 and ? = 7. (a) If a random sample of size n = 33 is drawn, find ?x, ? x and P(14 ≤ x ≤ 16). (Round ?x to two decimal places and the probability to four decimal places.) ?x = ? x = P(14 ≤ x ≤ 16) = (b) If a random sample of size n = 65 is drawn, find ?x, ? x and P(14 ≤ x ≤ 16). (Round ? x to two decimal places and the probability to four decimal places.) ?x = ? x = P(14 ≤ x ≤ 16) = (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 part (a) because of the sample size. Therefore, the distribution about ?x is .
