7) For women aged 18-24, systolic blood pressures (in mm Hg) are normally distributed with 7)
a mean of 114.8 and a standard deviation of 13.1. Find the probability of randomly
choosing one woman aged 18-24 whose mean systolic blood pressure is between 119 and
122.
Solve the problem.
8) For women aged 18-24, systolic blood pressures (in mm Hg) are normally distributed with 8)
a mean of 114.8 and a standard deviation of 13.1. If a group of 23 women aged 18-24 are
randomly selected, find the probability that their mean systolic blood pressure is between
119 and 122.
