Chapter 11, Problem 13P
Hypertension
The Update to the Task Force Report on Blood Pressure Control in Children [12] reported the observed 90th percentile of SBP in single years of age from age 1 to 17 based on prior studies. The data for boys of average height are given in Table 11.18.
Suppose we seek a more efficient way to display the data and choose linear regression to accomplish this task.
Fit a regression line relating age to SBP, using the data in Table 11.18.
TABLE 11.18 90th percentile of SBP in boys ages 1-17 of average height
*90th percentile for each 1 -year age group.
