Your boss at the local liquor store tells you that the sales of bottles of wine are directly related to the amount of shelf space allocated to it. He claims that as the amount of shelf space (as measured by the width of the display, in number of bottles) increases, so do sales. You decide to test this theory by varying the shelf space of your favorite bottle over the course of ten weeks, and measuring the sales each week. Here is your Excel output: Regression Statistics Multiple R 0.899025819 R Square 0.808247423 Adjusted R.
