A client scores a 17 total score on the BDI. The standard deviation is 5.7. The test-retest coefficient of the BDI total inventory is .93.
In this situation, the test-retest reliability indicates what? Is it poor validity or poor reliability? Does it indicate that the total test score will replicate with the exact same score the next time the client takes the inventory or does it indicate good reliability. Can you explain the rationale? 
The total BDI score of 17 (above) is which of the below:
1. The Observed Score plus error
2. The True Score plus error
3. 17
4. 1 and 2
5. 2 and 3
Discuss the rationale for this answer chosen. 
Calculate a confidence interval for these BDI results (above) and correctly state the interpretation of the total score of 17. Show the mathematical calculations using 3 decimal points in the calculations
