To identify the modal class from the given data, we need to determine which class interval has the highest frequency. Here are the frequencies for each class interval:
- 0-60 minutes: 8
- 61-120 minutes: 3
- 121-180 minutes: 0
- 181-240 minutes: 1
- more than 241 minutes: 2
The highest frequency is 8, which corresponds to the class interval **0-60 minutes**.
Therefore, the modal class for the distribution is **0-60 minutes**.
- 0-60 minutes: 8
- 61-120 minutes: 3
- 121-180 minutes: 0
- 181-240 minutes: 1
- more than 241 minutes: 2
The highest frequency is 8, which corresponds to the class interval **0-60 minutes**.
Therefore, the modal class for the distribution is **0-60 minutes**.
