L Learning Activity #3 Based on the following data, complete empty cells of the table by using Exponential Smoothing method. Then, Forecast the value of Month 6 and compute the MSE index. (a = 0.15 and consider the forecast of first month equal to 22). Month Real Forecast Forecast Squared observations forecast MSE error error 25 40 21 30 22 F = F-+ a(4- - F-1 MSE = n
