Question: Using the 911 call data in Problem 4 43 forecast calls

Using the 911 call data in Problem 4.43, forecast calls for weeks 2 through 25 with a trend-adjusted exponential smoothing model Assume an initial forecast for 50 calls for week 1 and an initial trend of zero. Use smoothing constants of α = .3 and β = .2. Is this model better than that of Problem 4.43? What adjustment might be useful for further improvement? (Again, assume that actual calls in week 25 were 85.)
