Heart Transplants	46.0	48.0	55.0	57.0	57.0

The director of medical services predicted 6 years ago that demand in year 1 would be 42.0 surgeries 

a) Using exponential smoothing with α of 0.1 and the given forecast for year 1, the forecasts for years 2 through 6 are (round your responses to one decimal place): 

Year	1	2	3	4	5	6
Forecast	42.0

For the forecast made using exponential smoothing with α = 0.90 and the given forecast for year 1. MAD =  _______ surgeries (round your response to one decimal place) 

b) Forecasts for years 4 through 6 using a 3-year moving average are (round your responses to one decimal place): 

Year	4	5	6
Forecast
