The National Football League (NFL) records a variety of performance data for individuals and teams. To investigate the importance of passing on the percentage of games won by a team, the following data show the average number of passing yards per attempt (Yds/Att) and the percentage of games won (WinPit) for a random sample of 10 NFL teams for the 2011 season (NFL website). Team Yds/Att WinPct Arizona Cardinals 6.7 Atlanta Falcons 6.1 36 Carolina Panthers 6.9 Chicago Bears 6.3 35 Dallas Cowboys 7.0 44 New England Patriots Philadelphia Eagles Seattle Seahawks 7.2 8.2 7.0 St. Louis Rams 5.0 6.8 238 23 53 66 12 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 won by the team. linear relationship between average number of passing yards per attempt and y = the percentage of games 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. WinPet (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 percentage of games won by the team increases by So, for every Select your answer of one yard in the average number of passes per attempt, the e. For the 2011 season, the average number of passing yards per attempt for the Kansas City Chiefs was was 8.4. Use the estimated regression equation developed in part (e) 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 Jon Key Chuck My Wick Question 1 of 1+
