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	9.00	8.00	11.00	13.00	14.00	15.00

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 6.00 for year 1

Year	1	2	3	4	5	6	7	8	9	10	11	12
Forecast (000)	6.00		nothing	nothing	nothing	nothing	nothing	nothing	nothing	nothing	nothing	nothing

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=6.00 is ___ registrations
