Hypertension The Second Task Force on Blood Pressure Control in Children [9] reported the observed 90th percentile of systolic blood pressure in single years of age from age 1 to 18 based on prior studies. The data for boys are given in Table 11.19. TABLE 11.19 90th percentile of systolic blood pressure (SBP) in boys ages 1-18 agoth 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. 11.30 Fit a regression line relating age to SBP, using the data in Table 11.19. Note: i=118xi=171,i=118xi2=2109,i=118yi=2124,i=118yi2=252,338,i=118xiyi=21,076 11.31 Provide a 95%Cl for the parameters of the regression line. 11.32 Do you think that the linear regression provides a good fit to the data? Why or why not? Use residual analysis to justify your answer. 11.33 What is the predicted blood pressure for an average 13-year-old boy as estimated from the regression line
