Response:

I picked this question because i enjoyed this one. I had to read it about 2-3 times to actually understand the question because it seems so overwhelming with all the numbers and the graph.. but actually, it was pretty easy.

Explanation:

The correct response was the one most frequently chosen. So what it's asking is for the percentage of those that got the right answer. So first you should figure out how many students there are in total. So you add all of them up.

-

300 + 1100 + 100 + 600 + 400 = 2500 students in total

-

Finding that the most frequently chosen answer was the one with 1100 students, I divided 1100 by 2500 (total students) in order to find out the percentage.
1100/2500 = 0.44

= 0.44

-

0.44 x 100 = 44 %

Answer = (E) 44
