The busiest time of the day at the Taco Town fast-food restaurant is between 11:00 a.m. and 2:00 p.m. Taco Town’s service is very labor dependent, and a critical factor for providing quick service is the number of employees on hand during this 3-hour period. To determine the number of employees it needs during each hour of the 3-hour lunch period, Taco Town requires an accurate forecasting model. Following are the number of customers served at Taco Town during each hour of the lunch period for the past 20 weekdays:
