Suppose we have samples of five men and of five women and have conducted a randomization test to compare the sexes on the variable . Further, suppose we have found that in 120 out of the 252 possible outcomes under randomization the difference in means is at least as large as the difference in the two observed sample means. Does the randomization test provide evidence that the sexes differ with regard to pulse? Justify your answer using the randomization results.
