For the forecast made using exponential smoothing with =0.6 and the given forecast for year 1,MAD= surgeries (round your response to one decimal place). Using exponential smoothing with a smoothing constant of 0.9 and the given forecast for year 1 , forecasts for years 2 through 6 are (round your responses to one decimal place): For the forecast made using exponential smoothing with =0.9 and the given forecast for year 1,MAD= surgeries (round your response to one decimal place). b) Use a 3-year moving average to forecast demand in years 4, 5, and 6 . Forecasts for years 4 through 6 using a 3-year moving average are (round your responses to one decimal place): For the forecast made using a 3-year moving average, MAD= surgeries (round your response to one decimal place). c) Use the trend-projection method to forecast demand in years 1 through 6 . Forecasts for years 1 through 6 using the trend-projection method are (round your responses to one decimal place): For the forecast made using the trend-projection method, MAD= surgeries (round your response to one decimal place). d) Based on the comparison of MAD, the best forecast is achieved using the method
