Answer:
Mode 1: 24-26 kilometers
Mode 2: 15-17 kilometers
Step-by-Step Explanation:
To find the modes of the grouped data (distance traveled by cyclists), we need to identify the class intervals with the highest frequencies, as these represent the modes.
Given data:
| Distance Traveled (km) | Frequency (f) |
|------------------------|---------------|
| 27-29 | 3 |
| 24-26 | 9 |
| 21-23 | 6 |
| 18-20 | 4 |
| 15-17 | 9 |
| 12-14 | 4 |
| 9-11 | 5 |
First, identify the class intervals with the highest frequencies:
- The class interval 24-26 and 15-17 both have a frequency of 9, which are the highest frequencies in the data.
Therefore, the modes of the grouped data are:
- Mode 1: 24-26 kilometers
- Mode 2: 15-17 kilometers
These class intervals represent the values with the highest frequencies in the dataset, indicating that these are the two possible modes of the data.
