Solution
Solution Steps
Step 1: Identify the Specified Class
The specified class for which the cumulative frequency is requested is 31-34.
Step 2: Locate the Specified Class in the Table
The specified class 31-34 is located at index 4 in the classes list.
Step 3: Sum Frequencies Up to the Specified Class
Starting from the first class, we sum the frequencies of all classes up to and including 31-34.
The frequencies of the classes up to 31-34 are [4, 4, 3, 6, 4].
The sum of these frequencies is 21.
Final Answer:
The cumulative frequency up to and including the class 31-34 is 21.
