So in this one, it's a conditional probability that our null hypothesis is false. And so let's construct another sampling distribution in the case where our null hypothesis is false. So let me just continue this line right over here, and I'll do that. So let's imagine a world where our null hypothesis is false, and it's actually the case that our mean is mu two. And let's say that mu two is right over here. And in this reality, our sampling distribution might look something like this. Once again, it'll be for a given sample size.
