The Billings Multi- Specialty Physician Group Practice is trying to forecast the number of patient visits it will have for the coming year. It has data from the previous three years to use for the forecast.

b. Develop a forecast for the next four quarters. Use whatever approach is appropriate given the pattern identified in thedata.
