Question

Suppose x has a distribution with ? = 14 and ? = 9.

(a) If a random sample of size n = 38 is drawn, find ?_x, ?_x and P(14 ≤ x ≤ 16). (Round ?_x to two decimal places and the probability to four decimal places.)

?_x =

P(14 ≤ x ≤ 16) =

(b) If a random sample of size n = 63 is drawn, find ?_x, ?_x and P(14 ≤ x ≤ 16). (Round ?_x to two decimal places and the probability to four decimal places.)

?_x =

P(14 ≤ x ≤ 16) =
