7. For women aged 18 to 24, systolic blood pressure (in mmHg) are normally distributed with a mean of 114.8 and a standard deviation of 13.1. (a) If a woman between the ages of 18 and 24 is randomly selected, what is the probability that her blood pressure is above 120? If 12 women in that age bracket are selected at random, what is the probability that their mean systolic blood pressure is greater than 120? (b)
