Carla and Patrisse began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Carla took a test in Math and earned a 77.7, and Patrisse took a test in English and earned a 68.7. Use the fact that all the students' test grades in the Math class had a mean of 71.2 and a standard deviation of 10.1, and all the students' test grades in English had a mean of 64.1 and a standard deviation of 9.9 to answer the following questions. a) Calculate the z-score for Carla's test grade. z=z= [Round your answer to two decimal places.] b) Calculate the z-score for Patrisse's test grade. z=z= [Round your answer to two decimal places.] c) Which person did relatively better? Carla Patrisse They did equally well.
