b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables?
The scatter diagram indicates a positive
✔ 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.

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 increase

Transcribed Image Text: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 (WinPct) for a random sample of 10 NFL teams for the 2011 season
(NFL website).
