Question: Critical Thinking Suppose x has a distribution with m 515 and s 514. (a) If a random sample of size n 5 49 is drawn,

Critical Thinking Suppose x has a distribution with m 515 and s 514.

(a) If a random sample of size n 5 49 is drawn, find m , s x x, and P(15 # x # 17).

(b) If a random sample of size n 5 64 is drawn, find m , s x x, and P(15 # x # 17).

(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).
