Maze. Psychology experiments sometimes involve testing the ability of rats to navigate mazes. The mazes are classified according to difficulty, as measured by the mean length of time it takes rats to find the food at the end. One researcher needs a maze that will take rats an average of about one minute to solve. He tests one maze on several rats, collecting the data shown. Time (sec) 38.4, 57.6, 46.2, 55.5, 62.5, 49.5, 38.0, 40.9, 62.8, 44.3, 33.9, 93.8, 50.4, 47.9, 35.0, 69.2, 52.8, 46.2, 60.1, 56.3, 55.1 a) Plot the data. Do you think the conditions for inference are satisfied? Explain. b) Test the hypothesis that the mean completion time for this maze is 60 seconds. What is your conclusion? c) Eliminate the outlier, and test the hypothesis again. What is your conclusion? d) Do you think this maze meets the “one-minute average” requirement? Explain.
