How big is a teaspoon? Many cookie recipes call for a teaspoon of dough to be dropped for each cookie. Eight randomly selected volunteer bakers baked a standard chocolate chip cookie recipe, making the cookies their usual “teaspoon” size. The number of cookies was recorded for each baker. Each volunteer was then given a new device that automatically dispenses a teaspoon of dough and then was asked to bake another batch of cookies, counting the results. At α = 0.10, is there a difference in the number of cookies per baker?
