So it looks like r is going to be less than zero, in a reasonable bit less than zero. It's going to approach this thing here. And if we look at our choices, so it wouldn't be r equals 0.65, these are positive, so I wouldn't use that one or that one. And this one is almost no correlation. r equals negative 0.02, this is pretty close to zero. So I feel good with r is equal to negative 0.72. r is equal to negative 0.72. Now I want to be clear, if I didn't have these choices here, I wouldn't just be able to say, just looking at these data points, without being able to do a calculation, that r is equal to negative 0.72.
