Question: A very large contribution to profits for a movie theater
A very large contribution to profits for a movie theater is the sale of popcorn, soft drinks, and candy.

For a month he varied the amount of time between movie showings and calculated the sales. Can the manager conclude that when the times between movies increase so do sales?
