(Please always round down the fractional numbers as forecasts). (b) Determine one-step-ahead forecasts for month 7 using exponential smoothing method with a = 0.1 and F1 = 200 (Please always round down the fractional numbers as forecasts but DO NOT round down intermediate values). (c) Determine one-step-ahead forecasts for month 7 using double exponential smoothing method with a = 0.1, B = 0.1, So = 100, and Go = 300 (Please always round down the fractional numbers as forecasts but DO NOT round down intermediate values).
