Week 1 2 3 4 5 6 7 8 9 10 Demand 20 23 29 38 24 28 37 24 26 28

a) The forecast for weeks 2 through 10 using exponential smoothing with

alpha =0.55 and a week 1 initial forecast of 20.0 are (round your responses to two decimal places):

b) for developing the forecast for week, two, the value to be used in the relationships are

c) for developing the forecast for week three the value to be used in the relationship are

d) the forecast forecast for week three using exponential smooth, smooth with alpha a= .55 and a week one initial forecast of 20.0 is (rounded your response to 2 decimal place)

e) for the forecast develop for week two through 10 years exponential smothering with Alpha equals 0.55 and a weak one initial forecast of 20.0 are :

f) mean absolute deviation is the average of the absolute zero. Based on the given information, the total absolute error for this development forecast=

g) for the forecast developing using exponential smoothening the MAD =
