If you know this one right over here, this one over here is not new information. And similarly, if you know these two, this guy over here isn't new information. You can always just calculate him based on the total and everything else. So that's the sense of why our degrees of freedom are the columns minus 1 times the rows minus 1. But anyway, so our chi-square statistic has 2 degrees of freedom. So what we have to do is, remember, our alpha value, let me get it up here. We had it right over here.
