Decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain your reasoning. For the 30 students who took the test, the high score was 80, the median was 75, and the low score was 40. Choose the correct answer below. A. The statement does not make sense because the median should lie halfway between the lowest value and the highest value. B. The statement makes sense because it is possible that when sorting the 30 scores from low to high, the first value was 40, the highest value was 80, and 75 was halfway between the 15th and the 16th score. C. The statement does not make sense because the median should divide the lowest fourth of a data set from the upper three-fourths. D. The statement makes sense because it is possible that when sorting the 30 scores from low to high, the first value was 40, the highest value was 80, and 75 was halfway between the 14th and the 15th score.
