Question: A local moving company has collected data on the number of moves they have been asked to perform over the past three years. Moving is highly seasonal, so the owner/operator who is both burly and highly educated, decides to apply the multiplicative seasonal method, (based on a linear regression for total demand) to forecast the number of customers for coming year.

a) What is his forecast for each quarter?

b) Is this the best method of forecasting for this data? Why or why not?
