Answer:
10
Step-by-step explanation:
The length of a class interval is the range of the upper boundary and the lower class boundary.
In our case the upper class boundary is the sum of upper class limit and 0.5, i.e.
99+0.5=99.5
The lower class boundary is the lower class limit less 0.5, i.e.
90-0.5=89.5
Therefore the length of this class interval is
99.5-89.5=10
