| 3.8 | 2.1 | 2.4 | 1.8 |
| 3.5 | 2.1 | 2.5 | 2.8 |
| 3.8 | 2.6 | 3.1 | 2 |
| 3.1 | 2.4 | 3.7 | 1.9 |
| 3.1 | 2.2 | 1.9 | 2.2 |
| 3.9 | 2.4 | 2.8 | 1.9 |
| 3.6 | 2.8 |
Assume that all distributions are normal, the four population standard deviations are all the same, and the data was collected independently and randomly. Use a level of significance of α=0.1α=0.1.
H0: μ1=μ2=μ3=μ4H0: μ1=μ2=μ3=μ4
H1:H1: At least two of the means differ from each other.
