Suppose x has a distribution with μ = 27 and σ = 19.
(a) If a random sample of size n = 42 is drawn, find μx, σx and P(27 ≤ x ≤ 29). (Round σx to two decimal places and the probability to four decimal places.)
| μx = |
| σx = |
| P(27 ≤ x ≤ 29) = |
(b) If a random sample of size n = 62 is drawn, find
μx, σx
and P(27 ≤ x ≤ 29). (Round
σx to two decimal places and the
probability to four decimal places.)
