Among the information in its top-50 list of the nation’s law schools, U.S. News & World Report provided two reputation scores (with maximum 5 5.0) for each school: one from academicians, the other from lawyers/ judges. The magazine also provided the most recent acceptance rate (%), student-faculty ratio (students/faculty), and the percentage of graduates who were employed immediately upon graduation. The data values are listed in file XR02067.
a. Construct a scatter diagram where the variables are the two kinds of reputation scores. Do schools given higher scores by the academicians seem to also receive higher scores from the lawyers/judges?
b. Fit a linear equation to the scatter diagram. Is the slope positive or is it negative? Is the sign of the slope consistent with your intuitive observation in part (a)?
