For women aged 18-24, systolic blood pressures ( in mm Hg) are normally distributed with a mean of 114.8 and a standard deviation of 13.1 ( based on data from the National Health survey. Hypertension is commonly defined as a systolic blood pressure above 140. If 4 women in that age bracket are randomly selected, what is the probability that their mean systolic blood pressure is above 140?

For women aged 18-24, systolic blood pressures (in mm Hg) are normally distributed with a mean of 114.8 and a standard deviation of 13.1. If 36 women are selected at random from a population of 300 women aged 18-24, find the probability that their mean systolic blood pressure will be less than 110 mm Hg. Assume that the sampling is done without replacement and use a finite population correction factor with N = 300 a. 0.0096 b. 0.0146 c. 0.3483...
