Section 3.3 Homework 

2.  If your score on your next statistics test is converted to a z​ score, which of these z scores would you​ prefer: −​2.00, −​1.00, ​0, 1.00,​ 2.00? Why?

1. The z score of 1.00 is most preferable because it is 1.00 standard deviation above the mean and would correspond to an above average test score.
2. The z score of −2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores.
3. The z score of 0 is most preferable because it corresponds to a test score equal to the mean.
4. The z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores.
5. The z score of −1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average test score.
