**Cumulative Frequency Calculation Based on Frequency Distribution Table**Below is a frequency distribution table displaying the number of students within specific age classes. Using this table, we can determine the cumulative frequency for a given age class.| Ages | Number of students ||-------|---------------------|| 15-18 | 10 || 19-22 | 8 || 23-26 | 4 || 27-30 | 2 || 31-34 | 5 || 35-38 | 4 |**Objective:**Based on the frequency distribution above, find the cumulative frequency for the class with lower class limit 31.**Explanation:**Cumulative frequency is the sum of the frequencies for all classes up to and including the given class. To find the cumulative frequency for the class with a lower class limit of 31, we must sum all the frequencies up to and including the class 31-34. **Steps:**1. Start from the first age class and add the frequency successively until the 31-34 class.2. The classes are: - Ages 15-18: 10 students - Ages 19-22: 8 students - Ages 23-26: 4 students - Ages 27-30: 2 students - Ages 31-34: 5 students**Cumulative Frequency Calculation:**CF = 10 (15-18) + 8 (19-22) + 4 (23-26) + 2 (27-30) + 5 (31-34)CF = 10 + 8 + 4 + 2 + 5 = 29So, the cumulative frequency for the class with the lower class limit 31 is 29.Please enter your answer rounded to one decimal place. **Enter your answer:**[Text Box for Input]**Question Help:**- [Video]- [Message instructor]
