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+            .
