For admission to graduate school, Kira is taking the physics subject-matter test, and Donna is taking the chernistry subject-matter test. Kira scored 646 on the physics test, and Donna scored 659 on the chemistry test. For each of these subject-matter tests, the distribution of scores is dearly bell-shaped. Scores for the physics test have a population mean of 605 points with a standard deviation of 34 points. Scores for the chemistry test have a population mean of 627 points with a standard deviation of 17 points. (a) Find the z-scores of Kira's performance as a score on the physics test and Donna's performance as a score on the chemistry test. Round your answers to two decimal places. Z-score of Kira's score:| Z-score of Donna's score:|| (b) Relative to her population, who scored higher? Choose the best answer based on the z-scores of the two test scores. O Kira O Donna It is unclear who scored higher relative to her population
