On one college aptitude test with a mean of = 100 and a standard deviation of s = 16, a student achieved a score of 124. The same student took a different test which had a mean of = 50 and a standard deviation of s = 10. On the second test the student achieved a score of 65. On which test did the student do better?

Can you please explain it so I know how to do it in the future, including breaking down how you arrived at your answer. If there was a formula used, can yo u please include that and how you arrived at that answer. Thank you
