Here are the data from the researcher studying the reaction times of rats. He has a requirement that the maze take about a minute to complete on average.

          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 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.
