The amount of time spent waiting for the bus at a city bus stop is symmetrically distributed.Eight randomly sampled people who catch the bus at this stop are asked how long they had to wait.Their wait times (in minutes) are:
Conduct a Wilcoxon signed-rank test to see if the median wait time is more than 20 minutes.Select the correct critical value (CV), test statistic (TS), and decision.(Use α = 0.05.)
A) CV = 6, TS = 4, reject H₀
B) CV = 30, TS = 4, fail to reject H₀
C) CV = 30, TS = 3, reject H₀
D) CV = 6, TS = 4, fail to reject H₀
