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. And then from this, we calculate the P value. And the way that we do the P value, remember, the P value is the probability of getting a sample proportion at least this extreme. And if it's below some threshold, we reject the null hypothesis and it suggests the alternative.
