Let's say that 1% is our threshold. We say, look, we're going to assume that the null hypothesis is true. There's some threshold that if we get a value any more extreme than that value, there's less than a 1% chance of that happening. So let's say we're looking at sample means, and we get a sample mean that is way out here. We say, well, there's less than a 1% chance of that happening, given that the null hypothesis is true. So we are going to reject the null hypothesis. So we will reject the null hypothesis.
