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.
