Re-solve problem 20 using a simple exponential smoothing model with α = .8, and with a 2-period moving average model. Which model is best?

Data From Problem 20:

Given the data shown below, use α = .1 and β = .2 to create a trend enhanced smoothing based forecast for period 6. Assume that FIT1 = 20 and T1 = 3.
