The manager of a local fast$-$food restaurant is interested in improving the service provided to customers who use the restaurant$$s drive$-$up window. As a first step in this process, the manager asks his assistant to record the time it takes to serve a large number of customers at the final window in the facility$$s drive$-$up system. The results are in the file P$07\_08.$xlsx$,$ which consists of nearly $1200$ service times. For this problem, you can assume that the population is the data in this file. Then the manager generates a simple random sample of size $30$ from the data in the Excel file in columns G and H$.$

Round your answers to two decimal places, if necessary.
