(8 points) Pockets! Jan and Amber are dissatisfied with the size of the pockets in the jeans that are marketed to women and they think it would make a great topic for a blog post. They decide to collect some data to see if their feeling that the pockets of women's jeans are indeed smaller than the pockets of men's jeans. In order to reduce the variability in their data, they decide to measure the pockets on jeans that are made to fit a person with a 32 inch waist. They look at 40 jeans in this size that are marketed to men, and 40 jeans that are marketed to women. They record the minimum width of the left back pocket of each jeans in centimeters. A summary of their results is shown in the table below.
