8. 8 Yds/Att Yds/Att C. WinPct D. WinPct 80- 80- 70- 70- 60 60 50 50- 40 40- 30 30 20 201. 10t 10- 8 Yds/Att Yds/Att - Select your answer - V b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? The scatter diagram indicates a - Select your answer - v linear relationship between = average number of passing yards per attempt and y = the percentage of games won by the team. c. Develop the estimated regression equation that could be used to predict the percentage of games won given the average number of passing yards per attempt. Enter negative value as negative number. WinPct = )(Yds/Att) (to 4 decimals) d. Provide an interpretation for the slope of the estimated regression equation (to 1 decimal). The slope of the estimated regression line is approximately . So, for every - Select your answer - v of one yard in the average number of passes per attempt, the percentage of games won by the team increases by %. e. For the 2011 season, the average number of passing yards per attempt for the Kansas City Chiefs was was 7.8. Use the estimated regression equation developed in part (c) to predict the percentage of games won by the Kansas City Chiefs. (Note: For the 2011 season the Kansas City Chiefs' record was 7 wins and 9 losses.) % (to 2 decimals) Compare your prediction to the actual percentage of games won by the Kansas City Chiefs. Considering the small data size, the prediction made using the estimated regression equation - Select your answer - V
