Thomas and Pablo began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Thomas took a test in Social Studies and earned a 74.8, and Pablo took a test in Science and earned a 64.1. Use the fact that all the students' test grades in the Social Studies class had a mean of 72.6 and a standard deviation of 9.3, and all the students' test grades in Science had a mean of 61.1 and a standard deviation of 9.8 to answer the following questions.
Calculate the z score for Thomas test grade.
B earns 11/20 of the profit.
(20-9)/20 = 11/20.
If the actual value is needed. You could do it one of two ways.
1---> 29000*11/20 = 15,950
2---> 29000*9/20 = 13,050
29,000 - 13,050 = 15,950
