Quizplus · Accepted Answer

The cumulative frequency for a class is calculated by adding up the frequencies of that class and all previous classes. In this case, the frequency for the class of 11-15 is 15, and the previous cumulative frequency was 184. Therefore, the current cumulative frequency is 199 (184 + 15). Choice C is the only option that matches this calculation.
