Based on prior knowledge, chronic heart failure is more common in older individuals. Therefore, it is expected that the feature AGE will have a higher distribution of older ages for patients with chronic heart failure compared to those without. 

To analyze this relationship, we can consider the AGE values for patients in each target class and determine the ranges that are commonly associated with chronic heart failure.

Here is the analysis and the resulting dictionary:

```json
{
    "no": [40.0, 45.0, 50.0, 55.0, 60.0],
    "yes": [60.0, 65.0, 70.0, 75.0, 80.0]
}
```

Explanation:
- The values listed under "no" represent 5 typical AGE values for patients without chronic heart failure.
- The values listed under "yes" represent 5 typical AGE values for patients with chronic heart failure. 

Keep in mind that these values are just examples and can vary depending on the specific dataset and its characteristics.
