Suppose x has a distribution with 𝜇 = 13 and 𝜎 = 11. (a) If arandom sample of size n = 38 is drawn, find 𝜇x, 𝜎 x and P(13 ≤ x ≤15). (Round 𝜎x to two decimal places and the probability to fourdecimal places.) 𝜇x =
𝜎 x =
P(13 ≤ x ≤ 15) =
(b) If a random sample of size n = 58 is drawn, find 𝜇x, 𝜎 x andP(13 ≤ x ≤ 15). (Round 𝜎 x to two decimal places and theprobability to four decimal places.) 𝜇x =

P(13 ≤ x ≤ 15) =
