Based on this graph, do you think there is a trend in the data? Explain.Look at the autocorrelation structure. Describe the critical values. Explain what these results tell you about the trending data.Based on what you found in parts 2 and 3, suggest a forecasting method you think might be appropriate for this series.Collect the quarterly data on the State Tax Collections: T10 Alcoholic Beverages Sales Tax for the state assigned to you on the sheet (Column CI):Prepare a time series plot of this series.

Determine the RMSE for your model during the historical period.Copy and paste the results to your estimates in column CC ( Gompertz model and logistic curves) show the data and output. Write down what you estimated and the idea behind it and what parameters used. Do not copy and example from image somewhere, these must have been estimated by you.
