the conditions for a chi squared. Tests are random, independent and expect accounts random being the observations randomly collected. So I need to like, make sure that when I'm picking people in the sample that picking a random sample where every next person is completely random and unbiased when how I picked the one prior independent the sample needs to be less than 10% of population. Um, because that means it's with replacement where we treat with replacement. And I means that we can assume that whether or not you feel a certain way about something has no impact will not next person does. So you would be independent to the next person, then expected counts needs to always be created equal of five. If we look at the choices you have in this problem, the only one of these three conditions that appear of our options is the randomness choice. So when it asked which of these choices, uh, supported kind of artistic the one that are, um, we used a random simple It's only the option talking about randomness where we're talking about using random sample, this is the only option we use. Um, the other ones don't fit anywhere with the remaining conditions
