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	5.00	5.00	9.00	8.00	7.00	10.00	13.00	14.00	17.00

Part 2

a) Calculate the forecasted registrations for years 2 through 12 using exponential smoothing, with a smoothing constant

()

of

0.40

and a starting forecast of

4.00

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)	4.00	4.44.4	5.45.4	5.35.3	5.25.2	6.76.7	7.27.2	7.17.1	8.38.3	10.210.2	11.711.7	13.813.8

Part 3

b) Mean absolute deviation based on the forecast developed using the exponential smoothing method (with a smoothing constant
