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.

There is an error in the file:
Stat 1: Set S has a positive range. (Should be set T has a positive range)

saw that, but figured it was a typo. Certainly ate up some time and made me feel stupid for missing a detail though.

I did the test just now and the error is not fixed yet. Set S --> Set T

[1 2 87] and [5 5 5] both fulfill statement 1 and 2,
but the mean is larger than the median in [1 2 87]
and the mean is equal to the median in [5 5 5]

(1) Set T has positive range.
(2) The elements of the set are not consecutive integers
(1) - range of any numbers from 1 to infininte - any clue of what numbers and how much numbers are in set T(2) - non concecutive - could be any range of nonconsecutive numbers from 1 to infinite (1)&(2) - still no additional information

As of yesterday, the typo in Statement 1 is correct in the forum, but it has not yet been corrected in the PDF, which should say:
(1) Set T has positive range.
instead of
(1) Set S has positive range.

I though that the range is always positive by definition....?

Hey guys! This is my first post on the forum. The current PDF has the first statement say: (1) Set S has positive range I think it is intending to say (1) Set T has positive range, Correct? Also - - - I've noticed all the previous posts are from more than a year ago, does anyone still use this?

(i) {-3, 8} R=8-(-3)=11 {10,12); R=12-10=2 Range is positive but we cant find out the T and hence the diff of the mean and median. (ii) {-3, 8} R=8-(-3)=11 {10,12); R=12-10=2 Even with the similar eg. (as above) which says that the values are non-consecutive, we can't find T. Together, we cant find T (E) wins
