Our subjects are 35-44-year-old males whose blood pressures are normally distributed with a mean 80 and standard deviation 12; which we can denote by N(80, 12). A borderline hypertensive is defined as a person whose diastolic blood pressure is between 90 and 95 mm Hg inclusive; what proportion of subjects are borderline hypertensive? A hypertensive is a person whose diastolic blood pressure is above 95 mm Hg; what proportion of subjects are hypertensive?
