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 = 19 wins
(d) x = 15 wins
