![**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 = 29
So, the cumulative frequency for the class with the lower class limit 31 is 29.
Please enter your answer rounded to one decimal place.
