Aaliyan and Lloyd began arguing about who did better on the tests, but they couldn't decide who did better given that they took different tests. Aaliyah took a test in Social Studies and earned a 79.8, and Lloyd took a test in Science and earned a 68.4. Use the fact that all the students' test grades in the Social Studies class had a mean of 74.1 and a standard deviation of 9.6, and all the students' test grades in Science had a mean of 60.9 and a standard deviation of 8.6 to answer the following questions. a) Calculate the z-score for Aaliyah's test grade. 2 = [Round your answer to two decimal places.] b) Calculate the z-score for Lloyd's test grade. [Round your answer to two decimal places.] c) Which person did relatively better? O Aaliyah O Lloyd O They did equally well.
