The time required to start a business, defined as the number of days needed to complete the procedures to legally operate a business, in 20 developed countries and 20 emerging countries is included in the accompanying table. Assuming that the population variances for developed countries and emerging countries are not equal, is there evidence of a difference in the mean time required to start a business between developed countries and emerging countries? (Use a = 0.05.) Compare these results to those from the test for equal means when the variances are assumed to be equal. Click the icon to view the data on the time to start a business. Let u, be the mean time required to start a business in developed countries and let 2 be the mean time required to start a business in emerging countries.
