(i) Explanation Calculation: Let variable x denotes the murder, and y denotes the arson. Procedure for assigned rank to data values: First combine both the samples. Arrange the data values in ascending order. Rank each of the data value in sequential order. The rank for each of tied data is computed as, First assign the sequential position ranks for all the values that are same. Take the mean of all the position ranks that are assigned for same data values. Assign the mean rank as the rank position for all the tied data. The assigned mean rank is used in calculating the test statistic. The ranks are, City x y x rank y rank 1 (ii) To determine (a) Find the level of significance. State the null and alternative hypothesis. (b) Find the value of the sample test statistic. (c) Find the P -value of the sample test statistic. (d) Mention the conclusion of the test. (e) Interpret the conclusion in the context of the application.
