 In this problem, we're given a series of data, and it's easy to do in StatCrunch. Just click on the little triangle, and it loads the data into StatCrunch. Then we go to Stat. I'm going to make this a little bit bigger, because we'll need the room a little bit later. So I'm just dragging these edges over. Anyway, we go back to Stat and SummaryStats, and then there are data in columns. So we select that to get variable one in there. Then I click on Mean, hold down the Control key in Standard Deviation. Select those two things we need, and it calculates the mean in Standard Deviation. And then I'm just going to compare, and you can see that we get the right answer for the mean in Standard Deviation. Of course, you've got to round.
