Is the average test score for Class A higher than the average test score for Class B? Statement 1: The median test score for Class A is 85, and the median test score for Class B is 80. Statement 2: All students in Class A scored between 70 and 95, and all students in Class B scored between 60 and 90.

A Statement 1 ALONE is sufficient, but Statement 2 ALONE is not sufficient.
B Statement 2 ALONE is sufficient, but Statement 1 ALONE is not sufficient.
C BOTH Statements 1 and 2 TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D NEITHER statement ALONE nor BOTH statements TOGETHER are sufficient.

✓ Correct Answer: Option D

Statement 1 (medians) doesn't guarantee the average. Statement 2 (ranges) doesn't tell us about the distribution within the range. Even together, knowing the median and range for each class does not provide enough information to definitively compare their averages, as skewness could vary.
