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	5.00	3.00	6.00	9.00	7.00	8.00	10.00	13.00	16.00	17.00

Part 2

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

()

of

0.30

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	4.34.3	4.54.5	4.14.1	4.64.6	6.06.0	6.36.3	6.86.8	7.87.8	9.39.3	11.311.3	13.013.0

Part 3

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

()

=

0.30

and a starting forecast of

F1

=

4.00)
