Question: An investigation of the effectiveness of an antibacterial soap in reducing operating room contamination resulted in the accompanying table. The new soap was tested in a sample of eight operating rooms in the greater Seattle area during the last year.
| Operating Room | ||||||||
| A | B | C | D | E | F | G | H | |
| Before | 6.6 | 6.5 | 9.0 | 10.3 | 11.2 | 8.1 | 6.3 | 11.6 |
| After | 6.8 | 2.4 | 7.4 | 8.5 | 8.1 | 6.1 | 3.4 | 2.0 |
At the 0.05 significance level, can we conclude the contamination measurements are lower after use of the new soap?
