    Are women's feet getting bigger? Retailers in the last 20 years have had to increase their stock of
    larger sizes. Wal-Mart Stores, Inc., and Payless ShoeSource, Inc., have been aggressive in stocking
    larger sizes, and Nordstrom's reports that its larger sizes typically sell out first. Assuming equal
    variances, at α = .025, do these random shoe size samples of 12 randomly chosen women in each
    age group show that women's shoe sizes have increased? (See The Wall Street Journal, July 17,
    2004.)
