At one university, the students are given z-scores at the end of each semester, rather than the traditional GPAs. The mean and standard deviation of all students' cumulative GPAs, on which the z-scores are based, are 2.5 and 0.5, respectively. Complete parts a through c. a. Translate each of the following z-scores to corresponding GPA scores: z=2.0, z=-1.0, z=0.5, z=-2.5. Translate z 2.0 to the corresponding GPA score. GPA=(Type an integer or a decimal.)
