Ed earned 88 on his math midterm and 84 on his english midterm. In his math class the mean score was 75 with standard deviation 8. In his english class the mean score was 73 with standard deviation 5. Convert each score to a standard score, then find which was the higher score relative to the rest of the class.
---------------------------------
Math z-score: (88-75)/8 = 1.625
-----
English z-score: (84-73)/5 = 2.2
--------------------
His English score is further above average and is a higher relative score.
