45...4-Period Moving Average and Simple Exponential Smoothing Forecast Model. The supply chain team first used a 4-period moving average to estimate future demand as shown in Figure 2.

a. What is the forecast for Periods 13-16 for the 4-Period Moving Average?

b. What is the forecast for Periods 13-16 for the Exponential Smoothing Model?

c. True/False: The error analysis of each model shown in Fig. 2 indicates that the 4-Period Moving Average model is superior to the Exponential Moving Average model in terms of Mean Squared Error (MSE).
