Frequency Distribution 3Ae949
1. **Problem Statement:** Dona conducted a survey among 140 Grade 7 students about their preferred Student Government presidents. The percentages for each candidate are given, and we need to create a frequency distribution table.
2. **Formula Used:** Frequency = (Percentage / 100) \times Total number of respondents
3. **Calculations:**
- Lloyd: $0.15 \times 140 = 21$
- Emily: $0.20 \times 140 = 28$
- Anne: $0.15 \times 140 = 21$
- Patricia: $0.15 \times 140 = 21$
- Emmanuel: $0.30 \times 140 = 42$
- Keith: Remaining percentage = $100\% - (15\% + 20\% + 15\% + 15\% + 30\%) = 5\%$
- Keith frequency: $0.05 \times 140 = 7$
4. **Frequency Distribution Table:**
| Candidate | Percentage | Frequency |
|-----------|------------|-----------|
| Lloyd | 15% | 21 |
| Emily | 20% | 28 |
| Anne | 15% | 21 |
| Patricia | 15% | 21 |
| Emmanuel | 30% | 42 |
| Keith | 5% | 7 |
This table shows the number of students who preferred each candidate based on the survey data.
