Assuming there is no trend, forecast sales for the four quarters of Year 5. Use seasonal indexes (rounded to 4 decimal places) from Part A. Report forecast answers as integers accurate to the nearest thousand. Quarter 1 forecast = 8 x thousand Quarter 2 forecast = 345 x thousand Quarter 3 forecast = thousand Quarter 4 forecast = x thousand Calculate the mean absolute percent error (MAPE) for the four forecasts. Use the integer forecast values you reported above. Report MAPE as percent accurate to 2 decimal places. Do not round intermediate values. MAPE = 35.33 X Question Help: Message instructor Submit
