Suppose x has a distribution with μ = 15 and σ = 11.
(a) If a random sample of size n = 43 is drawn, find μx, σ x and P(15 ≤ x ≤ 17). (Round σx to two decimal places and the probability to four decimal places.)μx =
σ x =
P(15 ≤ x ≤ 17) =
(b) If a random sample of size n = 74 is drawn, find μx, σ x and P(15 ≤ x ≤ 17). (Round σ x to two decimal places and the probability to four decimal places.)μx =
