For women aged 18-24, systolic blood pressures are normally distributed with a mean of 114.8 and a standard deviation of 13.

For women aged 18-24, systolic blood pressures are normally distributed with a mean of 114.8 and a standard deviation of 13.1. If 4 women between ages 18-24 are randomly selected, find the probability that their mean systolic blood pressure is greater than 140.

Solution: The following information has been provided: pr, 2 114.8, J = 13.1 We need to compute FILE 33 140}. The corresponding z-value needed to be computedis: X—p _ 140 — 114.3 Z: J 13.1...
