Based on the following data, complete empty cells of the table by using Exponential Smoothing method. Then, Forecast the value of Month 9 and compute the MSE index. (a=0.2 and consider the forecast of first month equal to 26). Month Forecast Forecast MSE Real observations Squared forecast error error 1 2. . 3 30 40 27 32 4 5 19 F, = F-1 +a(4_1-F_) 1-1 MSE = n
