The baseball team nearest to your home town is, once again, not doing well.Given that
your knowledge of what it takes to win in baseball is vastly superior to that of
management, you want to find out what it takes to win in Major League Baseball (MLB).
You therefore collect the winning percentage of all 30 baseball teams in MLB for 1999
and regress the winning percentage on what you consider the primary determinant for
wins, which is quality pitching (team earned run average).You find the following
information on team performance: (a)What is your expected sign for the regression slope? Will it make sense to interpret the
intercept? If not, should you omit it from your regression and force the regression line
through the origin?
