Data Sufficiency

Professor Vásquez gave a quiz to two classes. Was the range of scores for the first class equal to the range of scores for the second class?


(1) In each class, the number of students taking the quiz was 26, and the lowest score in each class was 70.
(2) In each class, the average (arithmetic mean) score on the quiz was 85.

Range is

highest number in the series - lowest number in the series

We are given the lowest number in statement 1

we are given the average in statement 2

we do not have the highest number/scores for both classes to find out the range of each class.
