The Armed Forces have two different programs for training aircraft personnel. A government regulatory agency has been commissioned to evaluateany differences which may exist between the two programs. The agency administers a standardized test to randomly selected groups of studentsfrom the two programs.Without making any assumptions about the distribution, can the agency conclude that there is a difference in the median test scores of students inthe two programs? Use the Wilcoxon rank-sum test to analyze the results.Standardized TestScoresProgram A Program B71896777817377988666101769281Copy DataStep 1 of 2: Find the value of the test statistic to test for a difference in the median test scores between the two programs.
