ix Suppose lectures; is measured in minutes as opposed to hours. Does this change the value of B2? Explain. x If you have n = 300 observations, what are the degrees of freedom of your regression? xi Suppose you introduce In (family income) and In(family income)? into the model. How would you interpret the partial effect of family income on grade? xii Suppose you have data for several cohorts of students over several years. In some years a lecturer strike happened during term time. Would you consider the variable strike a suitable instrumental variable for lectures? Explain.
iv In a study on undergraduate student grades in econometrics, the students are asked how many hours they spend each week on five activities: studying, attending lectures, sleeping, working and leisure. Any activity is put into one of five categories, so that for each student, the sum of hours in the five activities must be 168. Door the following model options of multiple linear regression grade; = Bo+B study+Belectures:+Bzsleepi+B.work+Byleisure+u; (2)
