Roger spent 45 minutes studying for the test. assuming the trend that exists in the data set below applies to roger as well, approximately which grade should roger expect to receive on the test? time spent studying (minutes) grade on test (%) 0 28 0 54 30 45 30 39 30 63 60 53 60 75 90 85 90 78 120 92 120 100 120 98 120 89 180 99 180 95 a. 22% b. 12% c. 60% d. 82%

If I am reading this correctly, the closest logical answer is C.

The students who studied 60 mins averaged between 53 and 75

He studied between that and 60% fits in that window.
