Question
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 times in seconds shown. a) Plot the data. Do you think the conditions are satisfied? Explain. b) Do you think this maze meets the requirement that the maze takes at most a minute to complete, on average? Perform the test with and without the outlier and write a couple of sentences to the experimenter about whether the maze meets the requirement. 38.2 46.3 62.6 37.8 63 33.8 50.3 34.9 52.9 60 54.9 O 57.5 55.6 49.3 41 44.2 93.7 48 69.4 46.3 56.2 a) Choose the correct histogram of the data below. OB.

Therefore, using the Student-t model for inference should be reliable. b) Write appropriate hypotheses for the test. Ho: µ= 60 HA: H<60 The test statistic for the full data is t= (Round to two decimal places as needed.)
