11. 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)	3.00	5.00	5.00	4.00	10.00	8.00	8.00	9.00	12.00	12.00	15.00

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

()

of

0.40

and a starting forecast of

6.00

for year 1 (round your responses to one decimal

place):
