how to solve exponential smoothing?

1. Forecasts based on averages. Given the following data: Number of Complaints 60 65 55 V 58 64 Period 1 2 3 4 5 Prepare a forecast for period 6 using each of these approaches: a. The appropriate naive approach. b. A three-period moving average. c. A weighted average using weights of .50 (most recent), .30, and.20. d. Exponential smoothing with a smoothing constant of .40. Below is the equation for Exponential Smoothing. Please treat F-A. (In this case, F=60.) F = A = 65 F=F+ a(A-1 - F_1) where F = Forecast for period t F1 Forecast for the previous period (i.e., period 1 - 1) a = Smoothing constant (percentage) A = Actual demand or sales for the previous period
