Consider the host/seater job in a full-service restaurant. Suppose that it takes an average of 2.5 minutes to greet a group of customers, check their reservation, and seat them. The expected number of new groups arriving during each hour on a particular day is given below.

a. Determine the number of hosts/seaters required during each hour. Round up if the number has a decimal.

b. Schedule three- to eight-hour-long shifts to cover the host/seater requirements you derived in part a. Use the shift scheduling heuristic.
