The forecasted demand for the week of October 12 using a 3-week moving average = 375.76 pints (round your response to two decimal places).
Using a 3-week weighted moving average, with weights of 0.10, 0.35, and 0.55, using 0.55 for the most recent week, the forecasted demand for the week of October 12 = 374.80 pints (round your response to two decimal places and remember to use the weights in appropriate ord
If the forecasted demand for the week of August 31 is 345 and = 0.20, using exponential smoothing, develop the forecast for each of the weeks with the known demand and the forecast for the week of October 12 (round your responses to two decimal places).

Answer:- The forecasted demand for the week of October 12 using a 3-week moving average = (381+368+378)/3 =375.67
Answer:- 3-week weighted moving average, the forecasted demand for the week of October 12 = (381*0.1+368*0.35+378*0.55)/(0.55+0.35+0.1)=374.8
Answer:-
Exponential smoothing forecasting = Ft = Ft-1 +(At-1-Ft-1)
= 0.2
September 7 forecast = Ft-1 +(At-1-Ft-1) =345 +0.2(345-345) =345
September 14 forecast = Ft-1 +(At-1-Ft-1) =345 +0.2(389-345) =353.8
September 21 forecast = Ft-1 +(At-1-Ft-1) =353.8 +0.2(408-353.8) =364.64
September 28 forecast = Ft-1 +(At-1-Ft-1) =364.64 +0.2(381-364.64) =367.91
October 5 forecast = Ft-1 +(At-1-Ft-1) =367.91 +0.2(368-367.91) =367.93
October 12 forecast = Ft-1 +(At-1-Ft-1) =367.93 +0.2(378-367.93) =369.94
KINDLY RATE THE ANSWER AS THUMBS UP. THANKS A LOT.
