Question

Quizplus · Accepted Answer

The total number of scores is 21 (above) + 6 (in the interval) + 18 (below) = 45. The median is the middle value, so it would be the 23rd score when arranged in order. Given the intervals, the 23rd score falls within the scores above the interval 51 to 59, not within the options given as A, B, or C.
