Suppose x has a distribution with ? = 19 and ? = 14.

(a) If a random sample of size n = 46 is drawn, find ?_x, ?_x and P(19 ≤ x ≤ 21). (Round ?_x to two decimal places and the probability to four decimal places.)

?_x =

P(19 ≤ x ≤ 21) =

(b) If a random sample of size n = 58 is drawn, find ?_x, ?_x and P(19 ≤ x ≤ 21). (Round ?_x to two decimal places and the probability to four decimal places.)

?_x =

P(19 ≤ x ≤ 21) =
