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. a. Fit a regression line relating age to SBP, using the data in Table 11.18. b. Provide a 95% confidence interval for the parameters of the regression line. c. What is the predicted blood pressure for an average 13-year-old boy as estimated from the regression line? d. What is the standard error of the estimate in the previous problem (3c)? e. Answer Problems 3c and 3d for a 17-year-old boy. f. Use residual analysis to check the goodness of fit to your model. Does your model provide a good fit to the data? Why or why not?
