Suppose that scores on an aptitude test are normally distributed with a mean of 100 and a standard deviation of 4.6. scores on a knowledge test are normally distributed with a mean of 70 and a standard deviation of 2.4. felix scored 106 on the aptitude test and 75 on knowledge test. which statement best describes felix's scores on the two tests comparatively?
answers:
felix's z-score on the aptitude test was 1.30. his z-score on the knowledge test was 2.08. felix performed better on the aptitude test, comparatively.
felix's z-score on the aptitude test was −1.30 . his z-score on the knowledge test was −2.08 . felix performed better on the aptitude test, comparatively.
