Forecasting Monthly Data. Consider the following time series data: a. Construct a time series plot. What type of pattern exists in the data? Be Specific and reference the correct time series description. b. Develop a three-week moving average for this time series. Compute MSE and a forecast for week 8. c. Use =.2 to compute the exponential smoothing values for the time series. Compute MSE and a forecast for week 25. d.Compare the three-week.moving average forecast with the exponential smoothing forecast using =.2. Which appears to provide the better forecast based on MSE?
