what is the class width for this histogram (and corresponding GFDT) Note: each class contains it's lower class limit, but not it's upper class limit.
I'm not really sure how to start this problem.

First we need to see the class boundaries.
These are 120,125,130,135,140,145.
It is given that each class contains it's lower limit but not upper limit.
All classes are spaced in intervals of 5 (e.g 125-120 = 5, 130-125 = 5 etc)
Therefore, the class width is 5.
