And then for this guy, it's going to be the same thing. His sample mean, 2 minus the mean of means squared plus, same thing for this guy, 2 minus the mean of means squared. Or another way to think about it, this is equal to 3 times 2 minus 4 squared, which is the same thing as 3. This is equal to 3 times 4 is equal to 12. And then we could do it for each of them. And actually, I want to find the total sum. So let me just write it all out, actually.
