Data set: Mice One major advantage of randomization/permutation tests over classical methods is that they easily allow the use of test statistics other than the mean.
a. Modify the program/macro you created in Question 9 to measure a difference in group medians instead of a difference in means for the female mice. Report the p-value and compare your results to those for Question 9.
b. You might also wonder if there is a difference in the variability in the groups. Modify the macro you created in Question 9 to test whether the variances of the female groups are equal. Report the p- value and state your conclusions.
