Last week Sarah had exams in Math and in Spanish. These exams were curved, so the grades were based on z-scores. On the math exam, the mean was M = 30 with SD = 5, and Sarah had a score of X = 45. On the Spanish exam, the mean was M = 60 with SD = 6 and Sarah had a score of X = 65. For which class should Sara expect the better grade?

There is not enough information to determine which is the better grade

The grades should be the same because the two exam scores are in the same location

Spanish

Math
