Now assume there is seasonality. Utilizing all the data below, use seasonality indexing as explained in class, to estimate the sales for each of the four quarters of 2016. We assume the total annual demand of J's clothing in 2016 is 2, 800 (unit:1000) or 2, 800,000. First compute the seasonal index for each quarter and make forecasts for 2016 using them.
