 If the historical demand for papers was a continuous distribution, in this case the news boy had records that showed that the demand for papers that he sold range from a low of 3,800 up to a high of 5,500. That appears to be a continuous distribution, but it is a uniform distribution and that is a straight line connecting the low and the high. So we need to model it a little bit differently. We don't use the ran function. We use the ran between function. And this is a function added to Excel in 2010, so hopefully you have it. And the ran between function takes two arguments, the low value and the high value. And it returns an integer randomly between those high and low values. It's an integer. You can see here as we calculate the sheet that it returns integers. And that will work for our situation since we don't have fractional newspapers. But in some models you might be working with dollars or something where you need to have decimals. And the way to do that is to modify our ran between formula to give it the number of decimal places we need. For dollars we need two decimal places, which would be 100s. So what we do, we multiply the low end by 100 and the high end by 100 and then we divide by 100. So we cancel out, but that gives us our decimal places. If we needed three decimal places, we would multiply by 1000 and then divide by 1000. So a little trick, but it'll convert the integers you normally get from ran between into the decimals you need for your particular problem.
