Let’s say that you like to go for walks around Pullman. However, every time you go down Grand Street, you can’t help but notice and be bothered by the broken Dissmore’s sign. You ask yourself, why can’t they just get it fixed? It’s not like they don’t have the money! After spending several sleepless nights, you decide enough is enough. You march down to Dissmore’s and have a friendly but serious chat with the manager. You dazzle the manager with your marketing expertise and statistics lingo, and convince her to get the sign fixed. The manager reviews the sales records and figures that customers visiting the store spent on average $35 per visit last year. This year, after finally getting the Dissmore’s sign fixed, the manager asks 30 customers how much they spent on average per visit. They report spending on average $40, with a standard deviation of $3. (Use an alpha of .10 to see if fixing the sign helped increase how much customers spend on average per visit at Dissmore’s.)
