And once again, this is a rule of thumb, but this is telling us that our actual sampling distribution might be skewed. Remember, this is just based on one sample, what we're able to figure out. This is one sample z interval. We might be wrong, but we wouldn't feel good that we're meeting the normal condition here. So I would rule this one out. Individual observations can be considered independent. Well, if he randomly selected people with replacement, then they could be independent.
