Find the corresponding area between z = 0 and each of the following: a. 2 = 0.96 b. Z=1.74 c. Z=2.18 d. Z=2.69 e. Z =3.00 Problems: I. Suppose you have the population values 50 and 80 and that their corresponding z-score are -1 and 2. respectively. Is it possible to determine the population's mean and standard deviation? If so, what are these values? If not, explain why it is impossible. 2. You have three grades in your report card that you want to interpret to your parents in terms of performance: Mathematic (75), English (85), and Science (90). The means are 72, 82, and 88, and the standard deviations are 3, 10 and 15, respectively. Is the information sufficient for you to compare your scores in each subject? If so, discuss the process. If not, explain why it is not possible
