So let's take 0.617, and we can even add, well, I'll just leave it there, times 1.65. So it's 1.02. I'll go with 1.02. This distance right here is 1.02. So what this tells us is that there is only a 5% chance that the difference, if we assume that the diet actually does nothing, there's only a 5% chance of having a difference between these two means, the means of these two samples, to have a difference of more than 1.02. There's only a 5% chance of that. Well, the mean that we actually got is 1.91.
