So there is a difference. So how would we go about testing this? Well, we've done hypothesis testing many times in many videos already. But here, we're going to sample from two different groups. So let's say that this is the population of right-handed folks, and this is the population of left-handed folks. Let's say from that sample of right-handed folks, I take a sample of 60, and then I do the same thing for the left-handed folks. And these don't even have to be the same sample sizes.
