Question
In a study designed to test the effectiveness of hypnosis in reducing pain a research team looked at responses from 8 randomly selected patients before and after hypnosis. The raw data are found in Table 1. Let ? = 0.01
Table 1: Perceived pain levels pre and post hypnosis for 8 subjects
| Pre | 9.6 | 11.3 | 10.6 | 8.5 | 9.8 | 12.8 | 10.8 | 12.2 |
| Post | 9.3 | 11.0 | 8.5 | 10.0 | 10.2 | 9.4 | 8.9 | 11.5 |
| Diff | -0.3 | -0.3 | -2.1 | 1.5 | 0.4 | -3.4 | -1.9 | -0.7 |
E) The point estimate for the true standard deviation of the effect that hypnosis has on pain perception is:
Note: round your answer to 3 decimal precision
G) The test statistic for this data set is:
Note: Round your answer to the nearest hundredth.
