The marketing manager of a firm that produces laundry products decides to test market a new laundry product in each of the firm's two sales regions. He wants to determine whether there will be a difference in mean sales per market per month between the two regions. A random sample of 13 supermarkets from Region 1 had mean sales of 75.2 with a standard deviation of 6.9. A random sample of 17 supermarkets from Region 2 had a mean sales of 81.1 with a standard deviation of 5.5. Does the test marketing reveal a difference in potential mean sales per market in Region 2? Let/11 be the mean sales per market in Region 1 and ? 2 be the mean sales per market in Region 2. Use a significance level of ? = 0.1 for the test. Assume that the population variances are not equal and that the two populations are normally distributed
