Data collected on the yearly registrations for a Six Sigmaseminar at the Quality College are shown in the following?table:
??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
Year | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
Registrations? (000) | 4.00 | 5.00 | 4.00 | 4.00 | 9.00 | 9.00 | 6.00 | 9.00 | 11.00 | 16.00 | 12.00 |
?a) Calculate the forecasted registrations for years 2 through12 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 | | | | | | | | | | | |
B.
The absolute deviation based on the forecast developed for eachperiod using the exponential smoothing method? (with a smoothingconstant (??) = 0.35 and a starting forecast of F1 = 4.00?) adds to (round your response to two decimal?places).
C.
Mean absolute deviation based on the forecast developed usingthe exponential smoothing method? (with a smoothing constant (??) =0.35 and a starting forecast of F1 = 4.00?) is
registration ?(round your response to two decimal?places).
