Steve got a T-score of 42 on a musical inaptitude test (recall that T-scores have a mean of 50 and a standard deviation of 10).

1. What would his Z-score, or standard score, be on this test?
2. Suppose that scores on this test correlates -.88 with the number of times people listen to songs online. What does this correlation tell us?
3. What would the predicted Z-score (Zy') be for the number of times people listen to Steve's song?
4. If, on average, 11,980 people listen to any given song online (with a standard deviation of 1,150), how many people would you predict would listen to Steve's song?
