Question

The accompanying data are the number of wins and the earned run averages (mean number of earned runs allowed per nine innings pitched) for

eight

baseball pitchers in a recent season. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not.
(a)
x=5
wins |
(b)
x=10
wins |
(c)
x=21
wins |
(d)
x=15
wins |

Wins, x Earned run average, y

20 2.71

18 3.31

17 2.62

16 3.82

14 3.95

12 4.43

11 3.73

9 5.03

The equation of the regression line is

y= x+ .
