Consider the following time series data. Week 1 2 3 4 5 6 Value 18 13 16 12 18 15 a. Construct a time series plot 1 Time Sorics Value 20 10 3 Week 2 Time Series Value 20 -10 5 Week 3 Time Series Value 20 10 5 Week - Select your answer - V What type of pattern exists in the data? - Select your answer - er. V b. Develop the three-week moving average forecasts for this time series. Compute MSE and a forecast for week 7 (to 2 decimals if necessary). MSE The forecast for week 7 c. Use a=0.2 to compute the exponential smoothing forecasts for the time series. Compute MSE and a forecast for week 7 (to 2 decimals). MSE The forecast for week 7 d. Compare the three-week moving average approach with the exponential smoothing approach using a = 0.2 Which appears to provide more accurate forecasts based on MSE? Explain. The three-week moving average provides a - Select your answer forecast than the exponential smoothing approach since it has a - Select your answer - MSE. e. Use a smoothing constant of a = 0.4 to compute the exponential smoothing forecasts. Compute MSE (to 2 decimals), Does a smoothing constant of 0.2 or 0.4 appear to provide more accurate forecasts based on MSE? Explain. The exponential smoothing forecast using a = 0.4 provides a - Select your answer forecast than the exponential smoothing forecast using a = 0.2 since it has a - Select your answer. VMSE
