to make histogram for the given data we have to find adjusted frequencies because class intervals have difference in their class size
so first take the the minimum class size that is,
=70-52=18
adjusted frequency of a class =minimum class-size/class-size ×frequency of the class
now see the attachment plz
than draw your histogram
