Quizplus · Accepted Answer

To find the percentage of incoming students that eventually go on to get a college education, we need to find the weighted average of the two groups:

(0.23)(0.46) + (0.77)(0.56) = 0.1058 + 0.4352 = 0.541 or 54.1%

Therefore, the best choice is D) 53.7% (rounded to the nearest tenth).
