12 Kimberly and Alexis began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Kimberly took a test in Math and earned a 76.4, and Alexis took a test in Social Studies and earned a 63.2. Use the fact that all the students' test grades in the Math class had a mean of 76.8 and a standard deviation of 9.9, and all the students' test grades in Social Studies had a mean of 62.6 and a standard deviation of 9 to answer the following questions.a) Calculate the z-score for Kimberly's test grade.z= [Round your answer to two decimal places.]b) Calculate the z-score for Alexis's test grade.

4. A college student is contemplating a possible career option. One factor that will influence his decision is the amount of money he is likely to make.

You are interested in seeing whether emotions impact decision making. You have three groups--a happy group, a sad group, and a neutral group. For the happy group there are 5 participants and the mean risky decision making score 5.0 with a standard deviation of 0.7. For the sad group there are 5 participants and the mean risky decision making score 5.4 with a standard deviation of 1.1. For the neutral group there are 5 participants and the mean risky decision making score 5.8 with a standard deviation of 2.8. The sum of squares between samples is equal to 1.6. The sum of squares within samples is equal to 38.0. You calculated the f-ratio above. The corresponding p-value for the f-ratio you calculated is p = 0.78. Is this finding significant?
