I need help with question 4 I will attach the table.

234 Chapter 7 . Demand Forecasting in a Supply Chain 4. Consider monthly demand for the ABC Corporation as shown in Table 7-3. Forecast the monthly demand for Year 6 using moving average, simple exponential smoothing, Holt's model, and Winter's model. In each case, evaluate the bias, TS, MAD, MAPE, and MSE. Which forecasting method do you prefer? Why? 5. For the Hot Pizza data in Exercise 2, compare the performance of simple exponential smoothing with a = 0.1 and a = 0.9. What difference in forecasts do you observe? Which of the two smoothing constants do you prefer? 6. Monthly demand at A&D Electronics for flat-screen TVs are as shown. Estimate demand for the next two months using simple exponential smoothing with a = 0.3 and 9. Quar Holt's model with a = 0.05 and B = 0.1. For the simple Afte fact
