Question 2: Run a SLRM regression of "Course_eval" over Beauty". (Course-eval is the dependent variable) a. What is the population equation? b. What is the regression equation? c. Is the coefficient of beauty" significant? Preform the hypothesis testing on paper? What is the null? What is the alternative? What does significance mean? d. What is the 95% confidence interval associated with the slope? What does this interval mean? e. What is the average of beauty in the data? (mean). Now according to your predicted equation, what is the predicted course-eval for a professor named Bob who has the average value of beauty? (find mean(beauty) and then insert that in the predicted equation on paper to find the predicted course-eval). f. What is the effect of Beauty on course-eval? (the slope) g. Do you think missing "experience" variable in regression 1 would cause omitted variable bias? Why? If yes, is the bias upward or downward? Why? h.
