The problem is to analyze a table showing the time that each of 40 students takes to travel to school. The table is given, and we are provided with the intervals of time and the corresponding frequencies.

1. Problem Description

The problem is to analyze a table showing the time that each of 40 students takes to travel to school. The table is given, and we are provided with the intervals of time and the corresponding frequencies.

2. Solution Steps

The table provides the following data:

- Time interval $0 < m \leq 10$, Frequency = 3

- Time interval $10 < m \leq 25$, Frequency = 18

- Time interval $25 < m \leq 40$, Frequency = 15

- Time interval $40 < m \leq 60$, Frequency = 4

The sum of the frequencies should be equal to the total number of students, which is

4

0. $3 + 18 + 15 + 4 = 40$. This verifies that the table is complete.

Without a specific question, there's no calculation to be done. However, the data in the table would allow one to calculate things like an estimate of the mean travel time, median travel time, etc., if a specific question were asked.

3. Final Answer

The given information is the time that each of 40 students takes to travel to school, presented in a frequency table. Without a specific question, there is no calculation to perform for the final answer. The given table represents the answer.
