Salvatore, as the director of a regional bank, is concerned about the wait times of customers at the four branches. He randomly selects 48 patrons at each branch and records the waiting time for each patron. The results of the samples are shown below. The Alvrine branch has a mean waiting time of 13.49 minutes with a standard deviation of 1.97 minutes. The Durham branch has a mean waiting time of 12.61 minutes with a standard deviation of 2.89 minutes. The Hanover branch has a mean waiting time of 11.06 minutes with a standard deviation of 2.46 minutes. The Mascomonet branch has a mean waiting time of 12.89 minutes with a standard deviation of 3.12 minutes.
