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=-0.523x+208.215. Use the data to answer the following questions. (a) Find the coefficient of determination, r2, and interpret the result. (b) Find the standard error of the estimate, se, and interpret the result. Goals Allowed, x Points, y 208 208 109 109 211 211 104 104 221 221 96 96 Part 1 (Round to three decimal places as needed.)
