Question
The accompanying data are the number of wins and the eamed 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
E Click the icon to view the table of numbers of wins and eamed run average.
The equation of the regression line is y-x+O
