Blood pressure readings are taken from a group of people who have no known medical issues. For men and women, the mean readings and related standard deviations (SDs) for systolic blood pressure (SBP) are shown by age group: If hypertension is defined as SBP 140 mm Hg, approximately what percentage of men age 35-44 in this sample will be classified as having hypertension, assuming a normal (Gaussian) distribution?
