Given the data shown below, use a -0.4 and 8 -05 to create a tend-enhanced exponential smoothing forecast assuming FIT - 23 and T1 - 2. Then use a=0.8 and F(t) = 23 to create a simple exponential smoothing forecast. Finally, create a 2 period moving average forecast V Period Demand 29 33 3 33 27 38 a.
