I'm assuming she used some type of a computer program to do it. Each time, once again, she just took the data that she had and she just rearranged it. She just reshuffled it. Maybe A on one day, maybe it gets this 18, maybe it gets the 25, maybe it gets a 30. Once again, so we've got the 18, the 25, and the 30, and maybe B gets the, and she's reshuffling all this other data points that I just have with dots, and maybe B, let's see, she got the 18, 25, and 30, maybe 12, 20, and 28. In this circumstance, this random reshuffling, and she keeps doing it over and over again, in this random reshuffling, the treatment group median minus the control group median is going to be what? It's going to be equal to positive five.
