A company's price/earnings (P/E) ratio is the company's current stock price divided by the latest 12 months' earnings per share. Suppose the following table shows the P/E ratios for a sample of 10 Japanese companies and 12 U.S. companies. Japan P/E Ratio 156 28 14 129 38 216 67 665 36 64 United States P/E Ratio 12 27 27 46 23 17 28 17 28 34 19 17 Is the difference between the P/E ratios for the two countries significant? Use the MWW test and ? = 0.01 to support your conclusion. State the null and alternative hypotheses.
