1) For women aged 18-24, systolic blood pressures are normally
distributed with a mean of 114.8 mm Hg and a standard deviation of
13.1 mm Hg.
a) If a woman was randomly selected from the population, what is
the probability that her blood pressure is between 119 and 122 mm
Hg? b) What is the blood pressure of a woman who is at the 65th
percentile? c) If 23 women aged 18-24 are randomly selected, find
the probability that their mean systolic blood pressure is between
119 and 122 mm Hg. d) Find the mean and standard deviation of the
sampling distribution of the sample sums of 23 women.
