The forecast for the next period (Jan) using a 3-month moving average approach = 20.67 sales (round your response to two decimal places). The forecast for the next period (Jan) using a 6-month weighted average with weights of 0.10, 0.10, 0.10, 0.20, 0.20, and 0.30, where the heaviest weights are applied to the most recent month= 20.0 sales (round your response to one decimal place). Using exponential smoothing with x = 0.40 and a September forecast of 21.00, the forecast for the next period (Jan) = sales (round your response to two decimal places).
