The accompanying data are the number of wins and the earned run averages (mean number of earned runs allowed per nine inningspitched) 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=10wins (c) x=21 wins (d) x=15 wins
the equation of the regression line is y = ? x + ? .
