a) construct a time series ploy. what type of pattern exists?
b) develop three quarter moving average forecats for this time series.
c) use a= .4 to compute the exponential smoothing vakues for the time series and provide forecasts
4) use a multiple regression model to develope an equation to account all types of patterns in data
5) orovide forecasts for spring semester of year 4, using all 3 techniques
6) clacukate MSE for all three techniques and determine the best forecasting method for this time series
