Anyway, with that said, let's figure out, if we assume that it has roughly a chi-square distribution, what is the probability of getting a result this extreme, or at least this extreme, I guess is another way of thinking about it. Or, another way of saying, is this a more extreme result than the critical chi-square value that there's a 5% chance of getting a result that extreme. So let's do it that way. Let's figure out the critical chi-square value, and if this is more extreme than that, then we will reject our null hypothesis. So let's figure out our critical chi-square value. So we have an alpha 5%. And actually, the other thing we have to figure out is the degrees of freedom.
