The monthly sales for Yazici Batteries, Inc., were as follows: Month Jan Feb Mar Apr May Jun Jul Aug Sept Oct Nov Dec Sales 19 21 17 15 15 18 16 19 22 20 20 24 This exercise contains only parts b and c. b) The forecast for the next month (Jan) using the naive method = 24 sales (round your response to a whole number). The forecast for the next period (Jan) using a 3-month moving average approach = 21.33 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 = 20.9 sales (round your response to one decimal place). Using exponential smoothing with a = 0.40 and a September forecast of 18.00, the forecast for the next period (Jan) = sales (round your response to two decimal places).
