Step-by-step explanation:

[tex][/tex] To construct a frequency distribution for the data, we first need to determine the range of the data and then decide on the number of classes to use.

Range of the data: 25 - 15 = 10

We can choose to use 5 classes for this data, with each class width being 2 hours.

Frequency Distribution:

| Homework Time (hours) | Frequency |

|-----------------------|-----------|

| 15-16 | 4 |

| 17-18 | 6 |

| 19-20 | 5 |

| 21-22 | 4 |

| 23-25 | 6 |

Note: The frequencies are obtained by counting the number of times each value falls within the specified class intervals.
