One can find online the amount each NHL team spent on players (in millions of dollars) for the 2011-12 NHL season and the total points each team earned by the end of the season. Figure 7.4, below, is a scatterplot of points earned against spending.
The equation of the least-squares regression line for predicting points earned from spending is
points = 66.5 + 0.43 x spending
Use the regression equation to predict the points earned if a team spent $50 million.
