But is the number of games won by a major-league baseball team in a season related to the team’s batting average? The table below shows the number of games won and the batting averages for 14 games in one American League season. Team Games Won, y Team Batting Average, x Cleveland 99 .293 New York 92 .288 Boston 85 .283 Toronto 74 .259 Texas 90 .284 Detroit 53 .256 Minnesota 78 .288 Baltimore 88 .274 California 70 .276 Milwaukee 80 .279 Seattle 85 .287 Kansas City 75 .267 Oakland 78 .265 Chicago 85 .281 a. If you were to model the relationship between the mean (or expected) number of games won by a major-league team and the team’s batting average x , using a straight line, would you expect the slope of the line to be positive or negative? Explain. b. Construct a scattergram of the data. Does the pattern revealed by the scattergram agree with your answer to part a? Construct a simple linear regression of the data using SPSS. What is the equation of the least squares line? c. Graph the least squares line on your scattergram. Does your least squares line seem to fit the points on your scattergram? d. Does the mean or expected number of games won appear to be strongly related to a team’s batting average? Explain. e. Interpret the values of and in the words of the problem.
Paper For Above instruction The relationship between a team's batting average and the number of games won is a fundamental aspect of baseball analysis, serving as a classic example of how statistical data can be used to assess team performance and predict future success. The hypothesis that there is a positive linear relationship—that higher batting averages are associated with more wins—is grounded in the intuitive understanding that better hitting leads to more runs and, consequently, more victories. In addressing part a, the expectation is that the slope of the relationship would be positive. This is based on baseball logic and prior empirical studies indicating that as batting averages increase, teams tend to win more games. Batting average, being a measure of a team's offensive efficiency, directly influences scoring opportunities. Therefore, a positive slope signifies that improvements in batting can lead to higher win
