Fit a regression line relating age to SBP, using the data in Table 11.18?

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.

Table 11.18: 90th percentile of SBP in boys ages 1ˆ’17 of average height

 

^a90th percentile for each 1-year age group.

Suppose we seek a more efficient way to display the data and choose linear regression to accomplish this task.
