Construct the frequency distribution table from the following data:
| Ages (in years) | Below 4 | Below 7 | Below 10 | Below 13 | Below 16 |
| No. of children | 7 | 38 | 175 | 248 | 300 |
State the number of children in the age group 10-13.
Solution:
The frequency distribution table from the given data:
| Class | Frequency |
| 0-4 | 7 |
| 4-7 | 31 |
| 7-10 | 137 |
| 10-13 | 73 |
| 13-16 | 52 |
Hence, the number of children in the age group 10-13 is 73.
