A researcher has observed independent samples of females and males, recording how long each person took to complete his or her shopping at a local mall. The respective times, in minutes, are listed in file. Using the 0.025 level of significance in a one-tail test, would females appear to exhibit more variability than males in the length of time shopping in this mall?
