Quizplus · Accepted Answer

To find the percentage of students who did well on the midterm and went bar hopping, we need to divide the number of students who did well and went bar hopping (22) by the total number of students who did well (81) and multiply by 100. This gives us (22/81) * 100 = 27.16, which rounds to 27.27%. Therefore, the best choice is B.
