And then there's going to be an alternative hypothesis that maybe your population mean is not equal to mu one. And you're gonna do something very simple. You take your population, take a sample of size N. Instead of calculating a sample proportion, you calculate a sample mean. And actually, you can calculate other things like a sample standard deviation. But now you have an issue. You say, well, ideally, I would use a Z statistic. And you could if you were able to say, well, I could take the difference between my sample mean and the assumed mean in the null hypothesis.
