b) Mean absolute deviation based on the forecast developed using the exponential smoothing method (with a smoothing constant () = 0.40 and a starting forecast of 4.00) is nothing registrations (round your response to one decimal place).

Data collected on the yearly registrations for a Six Sigma seminar at the Quality College are shown in the following table: Year Registrations (000) 1 4.00 2 7.00 3 3.00 4 4.00 5 9.00 6 7 8 9 10 8.00 8.00 10.00 13.00 12.00 12.00 a) Calculate the forecasted registrations for years 2 through 12 using exponential smoothing, with a smoothing constant (a) of 0.40 and a starting forecast of 4.00 for year 1 (round your responses to one decimal place): 2 3 5 6 9 10 11 12 Year Forecast (000) 4.00
