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 F1 = 6.00) is ____ 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 1 2 3 4 5 6 7 8 9 10 11 Registrations (000) 5.00 7.00 4.00 6.00 9.00 7.00 6.00 11.00 11.00 16.00 15.00 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 6.00 for year 1 (round your responses to one decimal place): Year 1 2 3 4 5 6 7 8 9 10 11 12 Forecast (000) 6.00
