What type of pattern exists in the data?a. develop the three-week moving average forecasts for this time series. compute MSeand a forecast for week 8.b. Use a = .2 to compute the exponential smoothing forecasts for the time series. compute MSe and a forecast for week 8.c. compare the three-week moving average approach with the exponential smoothing approach using a = .2. Which appears to provide more accurate forecasts based on MSe?d. Use a smoothing constant of a = .4 to compute the exponential smoothing forecasts.does a smoothing constant of .2 or .4 appear to provide more accurate forecasts basedon MSe? explain
