(a) If a random sample of size n = 50 is drawn, find πœ‡x, 𝜎 x and
P(15 ≀ x ≀ 17). (Round 𝜎x to two decimal places and the probability
to four decimal places.)
πœ‡x =
𝜎 x =
P(15 ≀ x ≀ 17) =
(b) If a random sample of size n = 68 is drawn, find πœ‡x, 𝜎 x and
P(15 ≀ x ≀ 17). (Round 𝜎 x to two decimal places and the
probability to four decimal places.)
πœ‡x =
𝜎 x =
P(15 ≀ x ≀ 17) =
