Suppose x has a distribution with μ = 27 and σ = 25

(a) If a random sample of size n = 37 is drawn, find μ_x, σ_x and P(27 ≤ x ≤ 29). (Round σ_x to two decimal places and the probability to four decimal places.

(b) If a random sample of size n = 58 is drawn, find μ_x, σ_x and P(27 ≤ x ≤ 29). (Round σ_x to two decimal places and the probability to four decimal places.)
