The waiting time (defined as the time costumer fall in line until he or she is finished with her/his transaction) of all costumers during this hour is recorded over a period of 1 week. A random sample of 20 costumers is selected, and the results are as follows: 5.21 4.35 4.02 5.43 3.77 4.34 4.54 3.90 5.10 6.05 5.46 6.29 4.79 2.45 3.69 5.15 4.20 5.10 3.12 1.38 At the 0.05 level of significance, is there evidence that the mean waiting time is less than 5 minutes?
