3-week moving average forecast of Week of Oct -12 = Average of last three months = (381+368+374)/3 = 374.33 pints
Weighted average forecast of 3 months = Sum of (Weights*actual of month) = 0.6*374+0.3*368+0.1*381= 372.90
Exponential Forecast below: Alpha = 0.2
For week of October 12 = 0.2 * 374 + (1-0.2) *374.33= 374.26
