Unformatted text preview: these data we can reject the null hypothesis. 7. If we hypothesize that X is positively related to Y after controlling for Time, based on these data we can accept the alternative hypothesis. For the following questions, consider regression model in which Y varies linearly with Time and with the Log of X. 8. Controlling for Time, a 3-percent increase in X is associated (on average) with a 26.132-unit change in Y. 9. Controlling for Time, the lower bound on a 95% confidence interval for the partial regression coefficient associated with X is 192.78835. For the following question, do not include Time in the analysis. 10. Consider a regression model in which Y varies as a polynomial function of X. If we know that the polynomial is less than degree 6, is the highest degree needed to optimally fit these data (based on minimizing the adjusted r-squared) is 4....
