The prices for the chip during the last 12 months were as follows: Month January February March April May June Price Per Chip $1.80 $1.61 $1.60 $1.85 $1.90 $1.95 Month July August September October November December Price Per Chip $1.80 $1.82 $1.60 $1.57 $1.62 $1.75 This exercise contains only part d. With a = 0.1 and the initial forecast for October of $1.78, using exponential smoothing, the forecast for periods 11 and 12 is (round your responses to two decimal places): Month Oct Nov Dec 1.75 Forecast $1.78 1.76 With a = 0.3 and the initial forecast for October of $1.76, using exponential smoothing, the forecast for periods 11 and 12 is (round your responses to two decimal places): Month Forecast Oct Nov $1.76 1.70 Dec 1.68 With a = 0.5 and the initial forecast for October of $1.72, using exponential smoothing, the forecast for periods 11 and 12 is (round your responses to two decimal places): Oct Nov Dec Month Forecast $1.72 1.65 1.64 Based on the months of October, November, and December, the mean absolute deviation using exponential smoothing where a = 0.1 and the initial forecast for October = $1.78 is $ 0.117 (round your response to three decimal places). Based on the months of October, November, and December, the mean absolute deviation using exponential smoothing where a = 0.3 and the initial forecast for October = $1.76 is $ 0.113 (round your response to three decimal places). Based on the months of October, November, and December, the mean absolute deviation using exponential smoothing where a = 0.5 and the initial forecast for October = $1.72 is $ 0.097' (round your response to three decimal places). Based on the mean absolute deviation, the better forecast is achieved using a = 0.5 . Video e Text Pages Calculator Similar
