Use the Wilcoxon signed-rank test to perform the required hypothesis test. Be sure to state the hypotheses and the significance level, to obtain the critical value(s), to compute the value of the test statistic, and to state your conclusion.
Last year, the mean waiting time for the number 14 bus was
This year, a random sample of 12 waits for the bus yielded the following waiting times, in minutes.
10.2 14.6 6.0 20.5 2.7 23.6
14.1 8.6 30.6 4.7 12.0 16.9
At the 1% significance level, do the data provide sufficient evidence to conclude that the mean waiting time this year is higher than last year's mean time of
