1. Apply the appropriate exponential smoothing model to create fit estimates of the monthly data below. Tell me why you selected the exponential smoothing model type.2. Adjust the model coefficient(s) to obtain the best estimates and calculate the residuals.3. Perform residual analysis using time series plots autocorrelation analysis histogram and a normality plot to determine if the residuals are random. Show the graphs. 4. State the hypothesis that you are testing relative to the residuals and make a clear statement about whether you accept or reject it. Show the statistics that support your conclusion.5. Calculate the RMSE and MAPE for the fit period.
