Question 14

_ _ One year Josh had the lowest ERA (eamedrun average, mean number of runs yielded per nine innings pitched) of any male pitcher at his school, with an ERAof 3.15. Also, Betty had the lowest Ques'hon "St I6 ERAof any female pitcher at the school with an ERAof 3.44. For the males. the mean ERAwas 3.711 and the standard deviation was 0.597. Forthe females, the mean ERAwas 4.944 and the standard deviation was 0.852. Find their respective z-scores. Which player had the better year relative to their peers, Josh or Betty?
