From the article:

> Unfortunately, if you’ve been observing the p-values, you’ve noticed that most have been very high, and therefore that test is not enough evidence that the tips/threats change the distribution

It doesn't look like these p values have been corrected for multiple hypothesis testing either. Overall, I would conclude that this is evidence that tipping does _not_ impact the distribution of lengths.

As demonstrated at the end... no positive or negative incentive gave one of the best answers in the grid. Whoop dee.
