Chapter 14.3, Problem 88E
In Exercises 14.88–14.97, we repeal the data and provide the regression equations for Exercises 14.48–14.57. In each exercise,
- a. compute the three sums of squares, SST, SSR, and SSE, using the defining formulas (Definition 14.6 on page 639).
- b. verify the regression identity, SST = SSR + SSE.
- c. compute the coefficient of determination.
- d. determine the percentage of variation in the observed values of the response variable that is explained by the regression.
- e. state how useful the regression equation appears to be for making predictions.
