     For major   elague baseball, describe the affect that an ERA has on a team’s winning   percentage. Ho: a team’s ERA does not affect the number of wins that a team   will accumulate; H1: a team’s ERA directly affects the number of wins that a   team will accumulate. The numerical hypothesis will look like this, Ho:   µ1=µ2; H1: µ1≠µ2.
