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?

Lina, either you reproduce the contents of the file so we can see the numbers, or you provide a link from where we can download the file for informtion. As Ms Sue said, it would not be possible to give further help if we don't see the data.
