Question

X Excel: Structured Activity- NFLPassing 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 data in the Excel Online file below show the conference (Conf), average number of passing yards per attempt (Yds/Att), the number of interceptions thrown per attempt (Int/Att), and the percentage of games won (Win %) for a random sample of 16 NFL teams for a season. Construct a spreadsheet to answer the following questions. Z-V D Open spreadsheet 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). Win%= bo +b Yds/Att b=60.9 02 N 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). Win% = bo +b .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). Win% = bo +b Yds/Att +b Int/Att Back

Answer 1

Answers -

a)

Regression Equation

Win% = -54.7 + 15.92 Yds/Att

b0 = - 54.7

b1 = 15.92

b)

Regression Equation

Win% = 96.1 - 1557 Int/Att

b0 = 96.1

b1 = - 1557

c)

Regression Equation

Win% = -3.9 + 12.88 Yds/Att - 1118 Int/Att

bo = - 3.9

b1 = 12.9

b2 = - 1118
