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