a. Use the 1995 to 2016 enrollments and simple exponential smoothing to forecast the 2017–2019 school enrollments. Use w = .8.

b. Use Holt’s method with w = .8 and v = .7 to forecast the 2017–2019 enrollments.

c. Apply the MAD, MAPE, and RMSE criteria to evaluate the two forecasting models of parts a and

b. Which model is better? Why?
