1/18/201742 MyMathLab Problem Set: Module FourCynthia McDonald11/1612.An author of a book discusses how statistics can be used to judge both a baseball player's potential and a team's abilityto win games. One aspect of this analysis is that a team's onbase percentage is the best predictor of winningpercentage. The onbase percentage is the proportion of time a player reaches a base. For example, an onbasepercentage of 0.3 would mean the player safely reaches bases 3 times out of 10, on average. For a certain baseballseason, winning percentage, y, and onbase percentage, x, are linearly related by the leastsquares regression equationx. Complete parts (a) through (d).y = 2.94− 0.4875(a) Interpret the slope. Choose the correct answer below.(b) For this baseball season, the lowest onbase percentage wasand the highest onbase percentage was. Does it make sense to interpret the yintercept?(c) Would it be a good idea to use this model to predict the winning percentage of a team whose onbase percentage was?(d) A certain team had an onbase percentage ofand a winning percentage of. What is the residual for thatteam? How would you interpret this residual?The residual for the team is. (Round to four decimal places as needed.)How would you interpret this residual?
