Chapter 5, Problem 19P

People are classified as hypertensive if their systolic blood pressure (SBP) is higher than a specified level for their age group, according to the algorithm in Table 5.1.

Assume SBP is normally distributed with mean and standard deviation given in Table 5.1 for age groups 1−14 and 15−44, respectively. Define a family as a group of two people in age group 1−14 and two people in age group 15−44. A family is classified as hypertensive if at least one adult and at least one child are hypertensive.

Table 5.1 Mean and standard deviation of SBP (mm Hg) in specific age groups

Chapter 5, Problem 19P, People are classified as hypertensive if their systolic blood pressure (SBP) is higher than a

What proportion of families are hypertensive? (Assume that the hypertensive status of different members of a family are independent random variables.)
