Suppose x has a distribution with 𝜇 = 15 and 𝜎 = 14.
(a) If a random sample of size n = 50 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 = 68 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 =
𝜎 x =
P(15 ≤ x ≤ 17) =
