So let's think about this a little bit. So we're going to start off assuming the null hypothesis is true. And in that assumption, we're going to have to pick a population proportion or a population mean. We know that for Bernoulli distributions, they're the same thing. And what I'm going to do is I'm going to pick a proportion so high so that it maximizes the probability of getting this over here. And we actually don't even know what that number is. And actually, so that we can think about it a little more intelligent, let's just find out what our sample portion even is.
