Problem III The following time series shows the sales of a clothing store over a 10-wook period. Sales (51000) 15 16 19 Week 1 2 3 4 5 6 2 8 9 19 20 19 22 15 10 1) Compute 3 week moving average for the above time series 2) Compute the mean square error (MSF) for the 3 week moving average forecast 3) Use 0.3 to compute the exponential smoothing values for the above time series 4) Compute the mean square error (MSC) for the exponential smoothing forecast 5) Develop linear trend expression for the above time series 6) Compute the mean square error (MSC) for the lineartrend forecast 7) Based on the MSE for each model developed above which one hits the best to the above time series? 8) Given the answer of question (7) forecast sales for week 11
