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 passing yards per attempt (Yds/Att), the number of interceptions thrown per attempt (Int/Att), and the percentage of games won following data show the conference (Conf), average number (Win%) for a random sample of 16 NFL teams for a season Team Conf Yds/Att Int/Att Win% Arizona Cardinals NFC 6.7 0.043 49.9 Atlanta Falcons NFC 0.022 62,4 7.1 Carolina Panthers NFC 7,2 0.033 37.2 Cincinnati Bengals AFC 6,0 0,027 56.2 Detroit Lions NFC 7.3 0.023 62.4 Green Bay Packers NFC 8.7 0.016 93.7 AFC Houstan Texans 7.7 0.020 62.7 Indianapolis Colts AFC 5.4 0.025 12.5 Jacksonville Jaguars AFC 4,7 0,032 31,4 Minnesota Vikings NFC 0.034 18.8 5.6 0.022 81.4 New England Patriots AFC 8.4 New Orleans Saints NFC 8.3 0.020 81.1 Oakland Raiders AFC 7.6 0.043 49.7 San Francisco 49ers 6.5 NFC 0.010 81.5 Tennessee Titans AFC 6.9 0.026 56,4 NFC 0.043 Washington Redskins 6.2 31.0 Washington Redskins 31.0 a. 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 (to 1 decimal). Enter negative value as negative number Yds/Att Win% b. Develop the estimated regression equation that could be used to predict the percentage of games won given the number of interceptions thrown per attempt (to 1 decimal). Enter negative value as negative number. Win% Int/Att 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 and the number of interceptions thrown per attempt (to 1 decimal). Enter negative value as negative number. Win% Yds/Att Int/Att + d. The average number of passing yards per attempt for the Kansas City Chiefs was 6.2 and the number of interceptions thrown per attempt was 0.036. Use the estimated regression equation developed in part (c) to predict the percentage of games won by the Kansas City Chiefs. (Note: For a season the Kansas City Chiefs' record was 7 wins and 9 losses.) Compare your prediction to the actual percentage of games won by the Kansas City Chiefs (to whole number). Actual percentage Predicted percentage -Select your answer-

Answer Preview

(a) Here X is YDS/ATT Y is Win % Sum ofX= 110.3 Sum ofY= 868.3 MeanX= 6.8938 MeanY= 54.2688 Sum of squares (SSX) = 19.1494 Sum of products (SP) = 316.1469 Regression Equation = =b
