1. The correct answer is: b)
Reason: by definition, a binary variable can assume only two values.
P.S.: As HOMEWORKLIB's policy if nothing is mentioned then only the first question is to be answered.
Thanks!

A nationwide, standardized test taken by high-school juniors and seniors may or may not measure academic potential, but we can nonetheless attempt to predict academic performance in college from scores on this test. We have chosen a random sample of 47 students just finishing their first year of college, and for each student we've recorded her score on this standardized test (from 400 to 1600) and her grade point average (on a four point scale) for her first year in...
