Suppose x has a distribution with x = 16 and 0 = 14. USE SALT (a) If a random sample of size n = 46 is drawn, find az, of and P(16 să s 18). (Round of to two decimal places and the probability to four decimal places.) P(16 S XS 18) - (b) If a random sample of size n = 65 is drawn, find algor ar gand P(16 5 s 18). (Round o to two decimal places and the probability to four decimal places.) 01- P(16 SX S18) (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 smaller than part (a) because of the larger sample size. Therefore the distribution about us is narrower
