Question

Finding the Equation of the Regression line and making predictions. Exercises 13-28 use the same data sets as Exercises 13-28 in Section 10-2. In each case, find the regression equation, letting the first variable be the predictor (x) variable. Find the indicated predicted value by following the prediction procedure summarized in Figure 10-5. Baseball Listed below are statistics from seven baseball teams. The statistics consist of the proportions of wins and the results of the difference: Difference = (number of runs scored)-(number of runs allowed for a recent year. Find the best predicted winning proportion for San Diego, which has a difference of 52 runs. Is the predicted proportion close to the actual proportion of 0.543?

Difference	163	55	-5	88	51	16	-214
Wins	0.6	0.5	0.5	0.5	0.5	0.51	0.383
