Evaluate: The higher the order number, the faster is the completion time.

[AlexisDerumigny]

Conclusion is that order1 has a significantly higher completionTime than all the 3 other orders, and that there is no significant differences between the orders 2, 3 and 4.

Here is the corresponding output:
