Question 3 out of 5 on Hospital data. Helpful tip: First, look at the exponential forecasting formula to understand that the forecast for the current period under exponential smoothing never depends on the current period's demand. Second, there are a series of questions using the same data. Therefore, save your calculations somewhere. Over the past several years, the number of patients visiting Hartville Hospital has steadily increased. The hospital administration is seeking the most accurate method for predicting patient demand in the coming years. The data for the previous five years are presented below: Compute the forecast for years 2 to 5 using exponential smoothing (Values P,Q,R, and S ). Use alpha = 0.6 . Let the initial forecast for year 1 equal the actual demand, which is 45 . Using the calculated forecasts, measure the errors, calculate the mean absolute deviation, and provide the answer for the mean absolute deviation. Your answer should be rounded to the nearest two decimal places. For example, if the answer is 12.15, enter 12.15. If the correct response is 12.868 , enter 12.87
