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.(Use α = 0.05.)
A) CV = 41, TS = 57, fail to reject H₀
B) CV = 41, TS = 28, reject H₀
C) CV = 71, TS = 57, fail to reject H₀
D) CV = 71, TS = 82, reject H₀
