Answer:

The forecasted demand for the week of October 12 using a 3-week moving average is 376,710

Explanation:

a) Data

21-Sep  383,383

28-Sep 368,368

5-Oct    378,378

Total  1,130,129

Average = 1,130,129/3 = 376,710

b) To calculate the moving average, the quantities for three weeks' demand are added and divided by 3.  This shows that the average demand for type A blood at the Damascus Hospital will be 376,710, going by the figures provided.  If the correct figures should have been 383, 368, and 378, the average would have equal to 376 pints.
