Homework Answers
The correct option is d.
From the given histogram we conclude that the distribution is negatively skewed.
Therefore median > mean
here mean = 
= 25
That is median > 25
Therefore option b and c are incorrect.
Also from the histogram maximum is less than 40
But in option a) it is greater than 40. So option a) also incorrect.
Therefore option d) is correct.
