Select the best answer choice. If the confidence interval for the slope in a regression model includes zero, this indicates an insignificant effect of the coefficient on the model. 

What is the exponentially smoothed forecast for 2023?  Round to two (2) decimal places and include appropriate units. If the forecast cannot be determined, state as such with a clear explanation as to why. 

EXTRA CREDIT: Consider and interpret the information shown for the exponential model. What can be concluded regarding the appropriateness of the model for the data? Include relevant details and value(s) to support your response.  Your analysis and interpretation should reflect what has been studied in this course as applicable to this problem. You will be evaluated on the accuracy and thoroughness of your response.

Partial credit is not given for incorrect or partially correct answers. 

Based on the concepts covered in the course, how should one choose the best regression model for the data?  Justify your response with conclusions from all the appropriate test(s) we studied and in the order they should be conducted.  I suggest: state the name of the test,  what the criteria is for passing the test, how an overall conclusion is determined You can write this in paragraph form or in bullet form.

Suppose that in a two-way ANOVA problem, you reject the null hypothesis for factor B and then conclude that there were no significant mean differences in the Tukey-Kramer procedure. Could this be possible? Under what circumstances could this be possible? Explain. Your analysis should reflect what has been studied in this course as applicable to this problem.

What is the best autoregressive model? What criteria was used to make this determination? Include the equation of that model in your response.  If no autoregressive model was found to be appropriate, clearly state as such with an explanation as to why. Your response should include any relevant details and values. Correctly round coefficients to four (4) decimal places.  Your analysis should reflect what has been studied in this course as applicable to this problem.
