Seven minus eight is negative one. Square that, you get one. And 16 divided by eight is going to be two. 25 divided by eight is going to be, let's see, that's 3 1 8, so that's 3.125. And then 1 8 is 0.125, 0.125. You add these together, so let's see, it's gonna be two plus 3.125, 5.125, plus another.125, so that's going to be 5.25. So our chi-squared statistic is 5.25.
