More on BMI and physical activity. Refer to Examples 10.3 (page 569) and 10.4 (page 572).
(a) What is the predicted BMI for a woman who averages 9400 steps per day?
(b) If an observed BMI at x = 9.4 were 24.3, what would be the residual?
(c) Suppose that you wanted to use the estimated population regression line to examine the predicted BMI for a woman who averages 4000, 10,000, or 16,000 steps per day. Discuss the appropriateness of using the equation to predict BMI for each of these activity levels.
