So both of those are more than 10, and so meets that condition. And then the last condition is, sometimes it'll called the independence test or the independence rule or the 10% rule. If you were doing this sample with replacement, so if she were to look at one song, test whether it's a female or not, and then put it back in her pile and then look at another song, then each of those observations would truly be independent. But we don't know that. In fact, we'll assume that she didn't do it with the replacement, and so if you don't do it with the replacement, you can assume rough independence for each observation of a song if this is no more than 10% of the population. And so it looks like it is exactly 10% of the population, so Della just squeezes through on our independence test right over there. So with that out of the way, let's just think about what the confidence interval is going to be.
