Quarterly figures for e-commerce retail sales were obtained from the first quarter of 2001 through the fourth quarter of 2007 (a total of 28 observations). A regression model was estimated to describe the trend in e-commerce retail sales over time. The Durbin Watson statistic was calculated as 1.727. Test to see if there is evidence of positive or negative autocorrelation. Use α = 0.10.

a. What is the Sample Regression Equation? b. Which of the independent variables are significant? Why? Use α = 0.10 in ALL questions. Use only the p-value to explain your answers (No need to go to tables). c. Test the overall significance of the model by relying on F Statistic. d. What is the value of adjusted r-square? e. Comment on the Normality assumption for the residuals for this model. In other word, has the normality assumption been satisfied? Explain...
