Using the table of data which contains the number of kWh used by the tenants in an apartment each month, we can obtain the frequency. The cumulative frequency is simply the previous frequencies added up. Among the choices, the correct answer is C.

Kilowatt Hours Frequency Cumulative Frequency
60-69 4 4
70-79 7 11
80-89 6 17
90-99 7 24
