A marketing research firm wishes to compare the prices charged by two supermarket chains-Miller's and Albert's. The research firm, using a standardized one-week shopping plan (grocery list), makes identical purchases at 10 of each chain's stores. The stores for each chain are randomly selected, and all purchases are made during a single week. It is found that the mean and the standard deviation of the shopping expenses at the 10 Miller's stores are X_1 = $ 121.92 and s_1 = 1.40. It is also a found that the mean and the standard deviation of the shopping expenses at the 10 Albert's stores are X_2 = $114.81 and s_2= 1.84. Assuming normality, test to see if the corresponding population standard deviations differ by setting a equal to .05. Is it reasonable to use the equal variances procedure to compare population means?
