Dr Brown Vs Dr Adams

by PAB2706 » Mon Mar 30, 2009 8:08 am
10 students took a chemistry exam that was graded on a scale of 0 to 100. Five of the students were in Dr. Adams’ class and the other five students were in Dr. Brown’s class. Is the median score for Dr. Adams’ students greater than the median score for Dr. Brown’s students?

(1) The range of scores for students in Dr. Adams’ class was 40 to 80, while the range of scores for students in Dr. Brown’s class was 50 to 90.

(2) If the students are paired in study teams such that each student from Dr. Adams’ class has a partner from Dr. Brown’s class, there is a way to pair the 10 students such that the higher scorer in each pair is one of Dr. Brown’s students.

B.

A's 40 50 60 70 80
B's 50 60 70 80 90

B suff... example was just to demostrate you know that what for each score in A B has higher value.

A can result in median less than, greater than or equal to B
