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.H0: The two populations of P/E ratios are not identical. Ha: The two populations of P/E ratios are identical.H0: Median for Japanese companies Median for U.S. companies 0 Ha: Median for Japanese companies Median for U.S. companies > 0 H0: Median for Japanese companies Median for U.S. companies > 0 Ha: Median for Japanese companies Median for U.S. companies = 0H0: Median for Japanese companies Median for U.S. companies 0 Ha: Median for Japanese companies Median for U.S. companies < 0H0: The two populations of P/E ratios are identical. Ha: The two populations of P/E ratios are not identical.Find the value of the test statistic.W = Find the p-value.
