(a) Exponentially smooth the time series using alpha = 0.4. Include the forecast value for the time series in period 6.
(b) If the observed value in period 6 is 31, what is the MAPE of the forecast values?
Exponentially smoothing:
Forecast value for the timeseries in period of 6 is 23.37
(B) MAPE = 0.22
