9) Five drivers were selected to test drive two makes of automobiles. The following table shows the number of miles per gallon for each driver driving each car. Drivers Automobile 3 30 49 4 27 31 30 21 32 B 36 35 30 onsider the makes of automobiles as treatments and the drivers as blocks, test to see if here is any difference in the mean miles/gallon of the two makes of automobiles. If, in art a, you concluded that at least one mean is different from the others, determine which mean is ifferent. Let a = 0.05.

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 Find the value of the test statistic. W = 15.16 X 15 28 15 28 39 17 15 Is the difference between the P/E ratios for the two countries significant? Use the MWW test and α = 0.01 to support your conclusion. State the null and alternative hypotheses. Ho: The two populations of P/E ratios are identical. H₂: The two populations of P/E ratios are not identical. O Ho: Median for Japanese companies - Median for U.S. companies 20 H₂: Median for Japanese companies - Median for U.S. companies 0 O Ho: Median for Japanese companies - Median for U.S. companies > 0 H₂: Median for Japanese companies - Median for U.S. companies = 0 O Ho: The two populations of P/E ratios are not…

Listed below are pulse rates (beats per minute) from samples of adult males and females. Find the mean and median for each of the two samples and then compare the two sets of results. D there appear to be a difference? Male: Female: 86 71 54 84 57 95 53 89 53 63 59 82 53 91 88 72 68 85 87 90 91 88 70 92 77 63 94 82 86 64 Find the means. The mean for males is 71.9 beats per minute and the mean for females is 80.6 beats per minute. (Type integers or decimals rounded to one decimal place as needed.) Find the medians. The median for males is 71 beats per minute and the median for females is 85 beats per minute. (Type integers or decimals rounded to one decimal place as needed.) Compare the results. Choose the correct answer below. OA. The mean and median appear to be roughly the same for both genders. OB. The mean and the median for males are both lower than the mean and the median for females. OC. The mean and the median for females are both lower than the mean and the median for males.…
