With the gasoline time-series data from the given table, show the exponential smoothing forecasts using ? = 0.1.

Prefer 0.1 or 0.2? for AB and C

GASOLINE SALES TIME SERIES Week Sales (1000s of gallons) 17 a. Applying the MSE measure of forecast accuracy, would you prefer a smoothing constant of a = 0.1 or a = 0.2 for the gasoline sales time series? Do not round your interim computations and round your final answers to three decimal places. a = 0.1 0 = 0.2 MSE Prefer: b. Are the results the same if you apply MAE as the measure of accuracy? Do not round your interim computations and round your final answers to three decimal places. a = 0.1 0 = 0.2 MAE Prefer: c. What are the results if MAPE is used? Do not round your interim computations and round your final answers to two decimal places. 0 = 0.1 0 = 0.2 MAPE % % Prefer
