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.

Transcribed Image Text: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
Click the icon to view the table of numbers of wins and earned run average.
The equation of the regression line is y=x+
(Round to two decimal places as needed.)
Construct a scatter plot of the data and draw the regression line. Choose the correct graph below.
