A check-processing center uses exponential smoothing to forecast the number of incoming checks each month. The number of checks received June was 42 million, while the forecast was 42 million. A smoothing constant of 0.15 is used. a) Using exponential smoothing and given a, the forecast for the month of July = million checks received (round your response to one decim place) b) If the check-processing center received 44 million checks in the month of July, then using exponential smoothing and given a, the forecast for 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's forecant is very hard to make an its processing requirements should have a very high variability B. the check-processing center should observe seasonality in its processing requirements OC. the check processing center should observe an increasing trend in its processing requirements OD. the check-processing center should observe a cyclical trend in its processing requirements
