Given
Box
Find
Which data set is represented by the box.
Step-by-step explanation
as we see from the given box ,
median = 6
lower quartile = 4
upper quartile = 8
so ,
now we see in the options ,
option D is incorrect as in this data set median is 7.
now see options A , B and C
in option A , '
lower quartile = 3+5/2 = 4
upper quartile = 7+8/2 = 7.5 , which is not correct
so , option A is also not correct
in option B
lower quartile = 3+5/2 = 4
upper quartile = 8+8/2 = 8 , which is correct.
hence , option B is correct
Final Answer
Hence , the correct option is B
