The cholesterol levels for U.S. women between the ages of 35 and 44 are distributed normally with a mean of 195 and a standard deviation of 37.7. Out of 200 randomly-selected women in this age group, about how many would you expect to have a cholesterol level greater than 185? Find the z score corresponding to the 60th percentile. Find the z-score that has 78.5% of the distribution’s area to its right.
