The Economist collects data each year on the price of a Big Mac in various countries around the world. Theprice of a Big Mac for a sample of McDonalds restaurants in Europe in May 2009 resulted in the following BigMac prices (after conversion to U.S. dollars): 3.80 5.89 4.92 3.88 2.65 5.57 6.39 3.24The mean price of a BigMac in the U.S. in May 2009 was $3.57. For purposes of this exercise, assume it is reasonable to regard thesample as representative of European McDonalds restaurants. Does the sample provide convincing evidencethat the mean May 2009 price of a Big Mac in Europe is greater than the reported U.S. price? Test the relevanthypotheses using a = .05.
