An animal researcher randomly assigns fifteen pigeons to each of five groups. The pigeons learn to peck at a colored disc for which they receive feed from a food dispenser. Each group is on a different schedule of reinforcement. At the end of a ten-day experimental period, the researcher records the number of pigeons who succeeded in reaching the criterion pecking rate of five pecks per second and the number who failed in each of the five schedule of reinforcement groups. She is interested in whether reaching the pecking criterion depends on type of reinforcement schedule. What frequency test would you choose to answer the question?
