A psychologist is designing an experiment in which rats will navigate a maze. Ten rats run the maze, and the time it takes for each to complete the maze is recorded. The results are as follows.

a. Following is a boxplot for these data. Is it reasonable to assume that the conditions for performing a hypothesis test are satisfied? Explain.

b. The psychologist hopes that the mean time for a rat to run the maze will be greater than 60 seconds. If appropriate, perform a hypothesis test to determine whether the mean time is greater than 60 seconds.
