Explanation Official Answer: E

Statement 1: In general, range can be 0 or positive. If set T has positive range, then all elements of the set are not equal. Not suff. Statement 2: If the elements of the set are not consecutive integers, then all elements of the set could or could not have equal values. NSF.

S1 and S2 taken together tell us that elements of the set are not all equal. These elements are not consecutive integers. This information does not is not sufficient to answer whether the median is greater than mean because the set could be {1, 1, 1, 1, 1, 2} or {2, 2, 2, 2, 2, 1}. Set {1, 1, 1, 1, 1, 2} has mean > median and set {1, 2, 2, 2, 2, 2} has median > mean. NSF. _________________
