Question: Ten chronically depressed psychiatric patients were administered the Beck Depression Index (BDI: a measure of depression) before and after electro-convulsive shock therapy (ECT) - higher BDI scores reflect greater levels of depression. With alpha set at .05, test to see if BDI scores changed significantly after the treatment.
| Patient | Pretest BDI | Posttest BDI |
| a | 3 | 1 |
| b | 4 | 3 |
| c | 5 | 3 |
| d | 5 | 4 |
| e | 6 | 5 |
| f | 7 | 5 |
| g | 8 | 4 |
| h | 9 | 5 |
| i | 9 | 6 |
| j | 15 | 5 |
