I want to find out what the undergraduate student body thinks about the move to Division I sports, which will involve higher student fees to support the athletic program. Every evening I go to Library Walk and I ask everyone who passes by whether or not they support the move to Division I, and get 1050 responses. From this data, I calculate the proportion that support moving to Division I. I find that only 25% of those surveyed support the move to D1.
