Question
Assume a normal curve and that the mean of the raw scores is 8, the standard deviation is 2.65, and the test-retest reliability is .84. If an individual who is in grade 5.6 received a score of 10, answer the following questions:
| 4 | 7 | 8 | 8 |
| 14 | 12 | 10 | 9 |
| 8 | 8 | 7 | 4 |
| 9 | 10 | 12 | 14 |
Refer to Exhibit 7-1. Scores with this instrument correlate .50 with 6thgrade GPA. If the 6thgrade GPA has a mean of 3.0 and a SD of .3, predict the GPA range this students grades will fall 68 percent of the time.
