So let's look at the frequency table below. So let's see, that's the frequency table, and let's see, there's three categories of computer time, just like they told us, minimal, moderate, and extreme. This is before they go to bed or at night. And then they have the three categories of how much they're sleeping, five or few hours per night, five to seven hours per night, or seven or more hours. 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.
