A check-processing center uses exponential smoothing to forecast the number of incoming checks each month. The number of checks received in June was 42 million, while the forecast was

41 million. A smoothing constant of 0.15 is used.

a) Using exponential smoothing and given , the forecast for the month of July = _______ million checks received (round your response to one decimal place).

b) If the check-processing center received 46 million checks in the month of July, then using exponential smoothing and given , the forecast for the month of August = __________ million checks received (round your response to one decimal place).

c) Exponential smoothing may not be an appropriate method to use for the check-processing center because:

A. the check-processing center should observe seasonality in its processing requirements.

B. the check-processing center should observe a cyclical trend in its processing requirements.

C. the check-processing center's forecast is very hard to make as its processing requirements should have a very high variability.

D. the check-processing center should observe an increasing trend in its processing requirements.
