8. 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 (please conform this by plotting a scatter plot of the data given below), 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 the coming year. Year 2 Year 3 Quarter Demand Quarter Demand Quarter Demand TTTTTT A regression analysis yielded this regression equation for total demand as y = 120.33+ 19* year. Please use it to determine the forecast for year 4 and then calculate the forecast for each quarter of year 4.
