And I'm picking that value for a reason. So I want the probability of Q2 being greater than 2.41. What I want to do is I'll look at a chi squared table like this. Q2 is a version of chi squared with 2 degrees of freedom. So I look at this row right here under 2 degrees of freedom, and I want the probability of getting a value above 2.41. And I picked 2.41 because it's actually at this table. And so most of these chi squared, the reason why we have these weird numbers like this instead of whole numbers or easy to read fractions, is it's actually driven by the p-value.
