So what we wanna do for this significance test is set up a null hypothesis and an alternative hypothesis. Now, your null hypothesis is the hypothesis that, hey, there's no news here. It's what you would expect it to be. And so if you read a report saying that 49% of teachers in the United States were members of labor unions, well, then it would be reasonable to say that the null hypothesis, the no news here, is that the same percentage of teachers in her state are members of a labor union. So that percentage, that proportion is P. So this would be the null hypothesis, that the proportion in her state is also 49%. And now what would the alternative be? Well, the alternative is that the proportion in her state is not 49%.
