A developmental psychologist tests the extent to which daily intake of fat (in grams) and amount of exercise (in minutes) can predict health (measured using a body mass index [BMI] scale in which higher scores indicate poorer health). Using the data given here, answer the following questions.

(a) Complete the F table and make a decision to retain or reject the null hypothesis that the multiple regression equation can be used to significantly predict health.
(b) Which predictor variable or variables, when added to the multiple regression equation, significantly contributed to predictions in Y (health)?

Fat (grams) Exercise (minutes)Health (BMI) 34 10 50 15 35 40 20 60 32 34 23 8 8 28 27 25
