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 a = average number of passing yar
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 avera
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
: of one yar
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 5.5. Use th
regression equation developed in part (c) to predict the percentage of games won by the Kansas City Chiefs. (Note: For th

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 is not too bad
