| Day | Quantity of paper per Machine | |||
| A | B | C | D | |
| 1 | 91 | 89 | 92 | 90 |
| 2 | 90 | 88 | 89 | 87 |
| 3 | 93 | 88 | 90 | 91 |
| 4 | 88 | 89 | 90 | 88 |

To test whether all four machines (A, B, C, D) are equally productive, we use one-way Analysis of Variance (ANOVA). The null hypothesis (H₀) is that the means of productivity for all machines are equal. The alternative hypothesis (H₁) is that at least one machine's mean productivity differs from the others.
