Emergency calls to Winter Park, Florida’s 911 system, for the past 24 weeks are as follows:

(a) Compute the exponentially smoothed forecast of calls for each week. Assume an initial forecast of 50 calls in the first week and use a = 0.1. What is the forecast for the 25th week?

(b) Reforecast each period using a = 0.6.

(c) Actual calls during the 25th week were 85. Which smoothing constant provides a superior forecast?
