A charter bus line has 48-passenger and 38- passenger buses. Let m48 and m38 denote the median number of miles traveled per day by the respective buses. With α = 0.05, use the Wilcoxon statistic to test H0: m48 = m38 against the one-sided alternative H1: m48 > m38. Use the following data, which give the numbers of miles traveled per day for respective random samples of sizes 9 and 11:
