Solution
The question you have uploaded appears to show a frequency table based on the weights of 80 students. The weight categories are divided into ranges (e.g., 30-34 kg, 35-39 kg, etc.), and the corresponding frequencies (the number of students in each range) are provided.
The table is as follows:
| Weight (kg) | Frequency |
|---|---|
| 30 – 34 | 8 |
| 35 – 39 | 10 |
| 40 – 44 | 13 |
| 45 – 49 | 17 |
| 50 – 54 | 14 |
| 55 – 59 | 1 |
| 60 – 64 | 7 |
To solve the questions based on this table, you might be asked to find things like:
- Mean (average) weight: This can be done using the midpoint of each weight class and calculating the weighted mean.
- Median: This would involve finding the cumulative frequency to determine the class interval where the median lies.
- Mode: The mode would be the class interval with the highest frequency.
- Standard Deviation: This would involve calculating the variance and then finding its square root.
Let me know which specific task or calculation you'd like to perform, and I can guide you through it!

Formulas
Mean = Σ(f * x) / N
Median = L + [(N/2 - F) / f] * h
Mode = L + [(f1 - f0) / (2f1 - f0 - f2)] * h
Standard Deviation = sqrt(Σ(f * (x - μ)^2) / N)
