So now this is the particular. We're comparing a dog to a particular dog to a particular wolf. We can put each of them on a weighing machine and come up with an absolute answer. There's no variability in this dog's weight, at least at the moment that we weigh it. No variability in this wolf's weight at the moment that we weigh it. So this is not a statistical question. So I'll put an x next to the ones that are not statistical questions.
