a -C 11. Two measures of a baseball player's effectiveness as a hitter are the number of hits he makes in a seasoff number of times he "bats in" a run (knows as "Runs Batted In" or RBIS). Can we predict a batter's RBIs from his hits? Below is numerical and graphical output from a computer regression of RBIs on Hits for 12 randomly selected Major League Baseball batters in 2017. 1 Ho: There is a linear relationship betw.
