Answer 1

Carl, Brian, Dave, and Ashley want very badly to attend the same university. Unfortunately only two spots remain and these four friends have the same GPA as well as virtually identical community service and leadership experiences. Therefore, the two spots will be determined by their SAT and ACT scores. Carl scored 1280 on the SAT, while Brian scored 1325. Dave scored 28 on the ACT, while Ashley scored 30. Use z-scores to determine which two students should be admitted. The mean SAT score was 1000 with a standard deviation of 175 and the mean ACT score was 20.6 with a standard deviation of 5.2. Both tests are normally distributed.

Answer 2

I know how to find the Z-scores i think
its the score-the average/standard deviation ?
