Here is the frequency distribution based on the given data, using a class size of 5 kg and 7 classes:

Would you like more details or have any questions?

Here are five related questions to extend your understanding:

1. How would the frequency distribution change if the class size was increased to 10 kg?
2. What is the total percentage of items in the 20.5 - 25.5 kg class?
3. How can you determine the cumulative frequency distribution from this table?
4. What are the midpoints for each class interval, and how are they useful?
5. How would you represent this data graphically (e.g., histogram or frequency polygon)?

Tip: When creating class boundaries, always subtract and add 0.5 to avoid ambiguity in data classification.
