Okay, so that's fair enough, so let's see what they want us to do. So they tell us, suppose there were 17 people in the study who were both in moderate computer users and got five to seven hours of sleep. So moderate, five to seven. So this category right over here, there were 17 people in this category over here. And just to mark that, let me, I copied and pasted this chart onto my scratch pad so I can write on it. So this group, they're telling us this group, and my pen is really acting up, I don't understand what's going on.
