![For admission to graduate school, Kira is taking the physics subject-matter test, and Donna is taking the chemistry 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 clearly 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.
- ( ) Kira
- ( ) Donna
- ( ) It is unclear who scored higher relative to her population](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F33c37e08-4ae0-47a0-8176-1da90542d3cc%2F4aecbc48-91ec-42ac-a41f-c5bd37836093%2Fwe0hsy_processed.jpeg&w=3840&q=75)

Expert Solution

Step 1
Given information-
For Physics-
Population mean, µ = 605
Population standard deviation, σ = 34
And for Chemistry-
Population mean, µ = 627
Population standard deviation, σ = 17
We have given that Kira scored 646 on the Physics test and Donna scored 659 on the Chemistry test.
We have to find the Z-score for both Kira and Donna.
