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 152 28 19 127 38 212 65 664 32 69 United States P/E Ratio 16 25 25 42 23 15 Find the value of the test statistic. W = 16 x 28 15 28 39 17 15 Is the difference between the P/E ratios for the two countries significant? Use the MWW test and a = 0.01 to support your conclusion. State the null and alternative hypotheses. O Ho: The two populations of P/E ratios are identical. H: The two populations of P/E ratios are not identical. O Ho: Median for Japanese companies - Median for U.S. companies 20 H₁: Median for Japanese companies - Median for U.S. companies < 0 O Ho: Median for Japanese companies - Median for U.S. companies ≤ 0 H: Median for Japanese companies - Median for U.S. companies > 0 O Ho: Median for Japanese companies - Median for U.S. companies > 0 H: Median for Japanese companies - Median for U.S. companies 0. O Ho: The two populations of P/E ratios are not identical. H: The two populations of P/E ratios are identical. Find the p-value. (Round your answer to four decimal places.) p-value = 0.0014 x State your conclusion. O Do not reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the P/E ratios for the two countries. O Reject Ho. There is sufficient evidence to conclude that there is a significant difference between the P/E ratios for the two countries. O Do not reject Ho. There is sufficient evidence to conclude that there is a significant difference between the P/E ratios for the two countries. O Reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the P/E ratios for the two countries.
