The table shows the number of goals allowed and the total points earned (2 points for a win, and 1 point for an overtime or shootout loss) by 14 ice hockey teams over the course of a season. The equation of the regression line is y= - 0.635x + 234.740. Use the data to answer the following questions (a) Find the coeficient of determination, , and interpret the result.
