1) Which is relatively better: a score of 88 on a Psychology test or a score of 45 on an Economics test? Scores on the Psychology test have a mean of 92 and a standard deviation of 10. Scores on the Economics test have a mean of 57 and a standard deviation of 5. Use measures of relative position to answer this exercise (Z-score).
Jeremiah earned a score of 530 on Exam A that had a mean of 450 and a standard deviation of 40. He is about to take Exam B that has a mean of 63 and a standard deviation of 20.
