Question

Brad and Tom are comparing their classes' scores on a math test. Both of their classes had mean scores of 80 on the test, but Brad's class had a range of 6 while Tom's class had a range of 30. If the highest possible score was 100, which class had the LOWEST score in it?

Responses
A Brad's class had the lowest score in it.
B The lowest score occurred in both classes.
C Tom's class had the lowest score in it
D It cannot be determined from the information.

Answer 1

D. It cannot be determined from the information given. The range only tells us the difference between the highest and lowest scores, but not necessarily what those scores are. Thus, we do not know which class had the lowest score.
