A student scores 74 on a geography test and 243 on a mathematics test. The geography test has a mean of 80 and a standard deviation of 5. The mathematics test has a mean of 300 and a standard deviation of 38. If the data for both tests are normally distributed, determine the z-scores for both distributions and decide on which test the student scored better relative to the other students in each class? z-score for geography class = [zscoreg] z-score for mathematics class = [zscorem] student performed better in [class] class.
