6. The mean waiting time at the drive-through of a fast-food restaurant from the time an order is placed to the time the order is received is 84.3 seconds. A manager devises a new drive-through system that he believes will decrease the wait time. He initiates the new system at his restaurant and measures the wait time for 10 randomly selected orders. The wait times are in the following table: 108.5 67.4 58.0 75.9 65.1 80.4 95.5 86.3 70.9 72.0...
