1.What proportion of the variation in number of wins is explained by the opponent's rushing yards? Express your answer as a proportion (between 0 and 1) written to 3 decimal places.

2.What is the sample correlation coefficient r? Write your answer to 3 decimal places.

3.What is the slope for the line of best fit? Write your answer to three decimal places.

4.What is the y-intercept for the line of best fit, written to two decimal places? (Here it is technically the wins-intercept.)

5.Predict the number of wins for a team if the opponent's total rushing yards were 1800 yards. Round your answer to the nearest whole number.
