You are the manager of a restaurant for a fast-food franchise.
Last month, the mean waiting time at the drive-through window for
branches in your geographical region, as measured from the time a
customer places an order until the time the customer receives the
order, was 3.8 minutes. You select a random sample of 81 orders.
The sample mean waiting time is 3.63 minutes, with a sample
standard deviation of 0.9 minute. Complete parts (a) and (b)
below.
