Bb. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables?The scatter diagram indicates a positivelinear relationship between a = average number of passing yarand 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 averapassing yards per attempt. Enter negative value as negative number.WinPct =||)(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 approximatelySo, for every increase: of one yarnumber 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 thregression equation developed in part (c) to predict the percentage of games won by the Kansas City Chiefs. (Note: For ththe 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 is not too bad The National Football League (NFL) records a variety of performance data for individuals and teams. To investigate the impassing on the percentage of games won by a team, the following data show the average number of passing yards per atand the percentage of games won (WinPct) for a random sample of 10 NFL teams for the 2011 season (NFL website).TeamYds/AttWinPctArizona Cardinals8.273Atlanta Falcons8.483Carolina Panthers7.149Chicago Bears7.149Dallas Cowboys7.662New England Patriots6.030Philadelphia Eagles5.726Seattle Seahawks8.074St. Louis Rams8.684Tampa Bay Buccaneers6.846a. Choose the correct a scatter diagram with the number of passing yards per attempt on the horizontal axis and the percwon on the vertical axis.

A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y=ax+b a=-0.859 b-37.904 r²-0.589824 r=-0.768 Use this to predict the number of situps a person who watches 11.5 hours of TV can do (to one decimal place)

You are studying how a penguin's flipper length (in mm) explains its body mass (in grams) using linear regression. You choose a non-directional alternative to be safe. You calculate an R2=0.7621. What is the interpretation of this value? O76.21% of the variability in body mass is explained by the flipper length. O 76.21% of the variability in flipper length is explained by the body mass. 0 Flipper length and body mass have a positive relationship becase R² is positive O76.21% of the body mass values will be inside the confidence interval

At the end of the semester the lecturer runs a regression using the student's final grade as the dependent variable and a male dummy (equals one if the student is male and equals zero otherwise) as the sole explanatory variable. If the estimated intercept is 67 and the estimated coefficient on the male dummy is -4 then what is the estimated mean mark for males in this course?
