1. A national achievement test is administered annually to 3rd graders. The test has a mean score of 100 and a standard deviation of 15. If Jane's z-score is 1.20, what was her score on the test? 2. Who has a better relative position: Tina's got a score of 75 on a statistics test with a mean of 60 and a standard deviation of 10 or Paula's got a score of 36 on accounting test with a mean of 30 and a variance of 16? 3. 23. A teacher gives a 20-point test to 10 students. The scores are shown here. Find the percentile rank of a score of 17. 18, 17, 12, 6, 8, 2, 3, 11, 21
