Also to find the P value
Thank you!!!
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 83.5 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...
