Textbook Question

Chapter 5, Problem 20P

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.

Chapter 5, Problem 20P, People are classified as hypertensive if their systolic blood pressure (SBP) is higher than a

Suppose a community has 1000 families living in it. What is the probability that between one and five families are hypertensive?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
