A group of 32 rats were randomly assigned to each of 4 dietslabelled (A, B,C, and D). Researchers measured the liver weight asa percentage of body weight (note: two rats escaped and anotherdied), resulting in the following data
| A | B | C | D |
| 3.42 | 3.17 | 3.34 | 3.65 |
| 3.96 | 3.63 | 3.72 | 3.93 |
| 3.87 | 3.38 | 3.81 | 3.77 |
| 4.19 | 3.47 | 3.66 | 4.18 |
| 3.58 | 3.39 | 3.55 | 4.21 |
| 3.76 | 3.41 | 3.51 | 3.88 |
| 3.84 | 3.55 | | 3.96 |
| 3.44 | | 3.91 |
Using the the Krusal-Wallis test, is there evidence, at asignificance level of 0.05, that the diet impacted the liver weightas a percentage of the body weight of the rats? Show theappropriate output from Minitab to support your claim. Note – youmay need to modify the format of the data in order to have it workin Minitab.
