1) Dr. Dumbledore decides to use these data to test whether there is a significant difference in mean distance walked between men with and without beards. What is the appropriate statistical test for him to use?
2) Carefully write down the null and alternative hypotheses for Dumbledore's test, being sure to define any symbols you use. (You may use words like "mu" in place of the Greek letter.)
3) Dr. Dumbledore conducts the test and (correctly) obtains a test statistic value of 0.5625. Either by computing a p-value or finding a critical value, determine whether you will reject or fail to reject the null hypothesis at α = 0.05. (Note: You must show your work enough to justify your answer for full credit; simply writing "reject" or "fail to reject" is not enough.)
4) Based on your answer to the previous problem, write one sentence summarizing the result of the test in the context of the problem.
