PROBLEMS:
- In a study conducted by the Department of Human Nutrition and Foods at Virginia Tech, the following data were recorded on sorbic acid residuals, in parts per million, in ham immediately after dipping in a sorbate solution and after 60 days of storage:
| Slice | Sorbic Acid Residuals in Ham | |
| Before Storage | After Storage | |
| 1 2 3 4 5 6 7 8 | 224 270 400 444 590 600 1400 680 | 116 96 239 329 437 597 689 576 |
Assuming the populations to be normally distributed, is there sufficient evidence, at the 0.05 level of significance, to say that the length of storage influences sorbic acid residual concentrations?
