The Armed Forces have two different programs for training aircraft personnel. A government regulatory agency has been commissioned to evaluate
any differences which may exist between the two programs. The agency administers a standardized test to randomly selected groups of students
from 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 in
the two programs? Use the Wilcoxon rank-sum test to analyze the results.
