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 85.4 seconds. A manager devises a new drive-through system that she believes will decrease wait time. As a test, she initiates the new system at her restaurant and measures the wait time for 10 randomly selected orders. The wait times are provided in the table to the right. Complete parts (a) and (b) below.	102.5	82.0
66.5	93.0
58.9	87.3
75.1	70.5
66.9	87.3
