Two minus 6.25 squared over 6.25. And I'll keep doing it. I'm gonna do it for all nine of these data points. And I actually calculated this ahead of time to save some time. And so if you do this for all nine of the data points, you're going to get a chi-squared statistic of 11.942. Now before we calculate the p-value, we're gonna have to think about what are our degrees of freedom. Now we have a three by three table here.
