Question

The following table gives the number of pints of type A blood used at Damascus Hospital in the past 6​ weeks:

Week Of   Pints Used
August 31   360
September 7   389
September 14   408
September 21   383
September 28   371
October 5   374

a) The forecasted demand for the week of October 12 using a​ 3-week moving average = pints ​(round your response to two decimal​ places).

b) Using a​ 3-week weighted moving​ average, with weights of 0.10, 0.30 , and 0.60, using 0.60 for the most recent​ week, the forecasted demand for the week of October 12​ = pints ​(round your response to two decimal places and remember to use the weights in appropriate order-the largest weight applies to most recent period and smallest weight applies to oldest period.​)

​c) If the forecasted demand for the week of August 31 is 360 and alpha= 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).
