And then maybe you have an alternative hypothesis that well, no, the population proportion is greater than that or less than that or it's just not equal to that. So let me just go with that one. It's not equal to P sub one. And then what we do to actually test, to actually do the significance test is we take a sample from the population. It's going to have a sample size of N. We need to make sure that we feel good about making the inference. We've talked about the conditions for inference in previous videos multiple times. But from this, we calculate the sample proportion.
