Let's solve the questions based on the provided frequency distribution table.

### (i) What is the class interval for classes 31 – 35?

- **Class interval** is the range of values in a class. For the class 31 – 35, the **lower limit** is 31, and the **upper limit** is 35.
  
Thus, the **class interval** for 31 – 35 is:
\[ 35 - 31 = 4 \]
So, the class interval is **5** units (since it includes both 31 and 35).

### (ii) How many students are there in the range of 41–45 kgs?

From the table, the class for weights **41 – 45** has **14 students**. 

So, the number of students in the range 41–45 kgs is **14**.

### Follow-up Questions:

1. How do you calculate the midpoint of a class interval?
2. What is the total number of students in all classes combined?
3. How can you find the frequency density of each class interval?
4. What would be the cumulative frequency for the class interval 41–45?
5. How can the mode be estimated using the frequency distribution?

### Tip: 
To calculate the frequency density, divide the frequency by the class width (interval).

What is the class interval for classes 31 – 35? How many students are there in the range of 41–45 kgs?

Learn how to calculate the class interval for the 31–35 kg weight range and find out how many students weigh between 41–45 kg based on a frequency distribution table. This problem covers key statistical concepts suitable for students in Grades 6-8.
