Question

Maze Psychology experiments sometimes involve testing

the ability of rats to navigate mazes. The mazes are clas-
sified 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.
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.
