Consider the data given for the Smith Agency water usage in problem 1 .

a. Determine the forecast for the upcoming January if exponential smoothing is used with a smoothing constant of a = . 1 .

 b. Repeat part a using a = .6

 c. Using the criterion of minimizing the mean squared forecast error, which smoothing constant, a = . 1 or a = .6 , appears to give better results?
