A corporation wishes to evaluate the effectiveness of a new employee training program. Workers on two independent assembly lines are monitored, and the amount of time (in minutes) to complete a standardized assembly procedure is recorded for each. The distribution of assembly times is known to be heavily left-skewed. Based on the given sample information, does it appear that the training program is associated with a reduced median assembly time? Use the Wilcoxon rank-sum test to make your decision. Select the correct critical value (CV), test statistic (TS), and decision. (Useα= 0.05.)
