Use the cross-sectional data in lawschool.xlex or lawschool.dta found from MyCourses (covering 136 law schools), and do the following:a) Report the estimated linear regression model. b) What is the predicted ceteris paribus difference in salary for schools with median LAST different by 5 points? (Report your answer as a percentage). c) Interpret the coefficient of the variable log(cost). d) How much is a difference in ranking of 10 worth in term of the predicted salary
