He begins by using a team's earned run average (ERA), a measure of pitching performance, to predict the number of wins. He collects the team ERA and team wins for each of the 30 Major League Baseball teams. A. Assuming a linear relationship, use the least-squares method to compute the regression coefficients bo and bi B. Predict the mean number of wins for a team with an ERA of 4.50. C. Compute the coefficient of determination D. Perform a residual analysis on your results and determine the adequacy of the fit of the model. (L.I.N.E) E. At the 0.05 level of significance, is there evidence of a linear relationship between the number of wins and the ERA? F. Construct a 95% confidence interval estimate of the mean number of wins expected for teams with an ERA of 4.50. G. Construct a 95% prediction interval of the number of wins for an individual team that has an ERA of 4.50. H. Construct a 95% confidence interval estimate of the population slope.
