1. **Problem:** Construct a frequency distribution table for the weekly physical training hours of 30 soldiers with data: 3, 4, 5, 6, 7, 8, 3, 4, 5, 6, 7, 8, 4, 5, 6, 7, 8, 5, 6, 7, 8, 4, 5, 6, 7, 3, 4, 5, 6, 7. 2. **Formula and rules:** Frequency distribution groups data into classes and counts occurrences in each class. Here, data ranges from 3 to 8, so classes can be single values: 3, 4, 5, 6, 7, 8. 3. **Step-by-step:** - Count occurrences of each value: - 3 appears 3 times - 4 appears 5 times - 5 appears 6 times - 6 appears 6 times - 7 appears 6 times - 8 appears 4 times 4. **Frequency distribution table:** | Hours | Frequency | |-------|-----------| | 3 | 3 | | 4 | 5 | | 5 | 6 | | 6 | 6 | | 7 | 6 | | 8 | 4 | 5. **Explanation:** Each class represents a training hour value, and frequency is how many soldiers trained that many hours. This table summarizes the data clearly.
