Solution

To find the class boundaries you need to know the GAP. Its means, know at leats two class. For Example, your class in the question is 8.24-13.36, you have to know the class before of next, for example 13.4-18.52. The GAP should be 13.4 - 13.36=0.04, then the boundary would be the half of the GAP; 0.04/2= 0.02

Its means the Lower Boundary would be 8.24 - 0.02= 8.22, and the upper boundary would be 13.36 + 0.02=13.38, but you would be to know the after o nets class.

For this exercise, the width is 13.36 - 8.24=5.12

And the mid point is 8.24+(5.12/2)= 8.24+2.56= 10.80
