So B) has all the requirements

The vertical line in the box represents the mean which if you add all the numbers and divide by 15 you get 17 and since no other whisker box plot doesn't have 17 as its mean B is the only logical answer
15,8,5,18,20,11,30,28,9,15,17,24,15,28,26

put in order

5,8,9,11,15,15,15 ,17, 18,20,24,26,28,28,30

median = 17
answer is B
