Suppose x has a distribution with = 14 and a = 12. LUSE SALT (a) If a random sample of size n-37 is drawn, find , a and P(14 sxs 16). (Round o; to two decimal places and the probability to four decimal places.) P=1 9x= P(14 x 16) = (b) If a random sample of size n 57 is drawn, find and P14 SxS 16). (Round ato two decimal places and the probability to four decimal places.) # 0- P(14 5 X 516) (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).) sample size. Therefore, the distribution about ; is-Select The standard deviation of part (b) is Select-part (a) because of the Select- Jala?. Baadh Watch
