Quizplus · Accepted Answer

Class boundaries are calculated by finding the midpoint between the upper limit of one class and the lower limit of the next class. For the class 80.0-110.9, the lower boundary is halfway between 80.0 and the next lower value (which isn't given, but assuming a consistent class width, it would be 79.95), and the upper boundary is halfway between 110.9 and 111.0, which is 110.95.
