Problem 7 (Scott Frazier and Dana Leindecker)

Observe 5 men and 5 women purchasing frozen yogurt from Yogurtland (be inconspicuous, you don't want to let the cashier know you're watching the process). Record whether or not they are given stereotypically feminine-colored (pink/purple) or stereotypically masculine-colored (blue/green) spoons. Compare the ratio of feminine to masculine spoons given to each gender. Does there seem to be a gender bias?

Assume that the cashier starts the day with 50 pink spoons and 50 blue spoons. If 50 women and 50 men purchase yogurt throughout the day, what color spoon will run out first?
