Based on prior knowledge, the relationship between age and the presence of chronic heart failure (CHF) can be analyzed. 

Commonly, the prevalence of CHF increases with age. Typically, older adults are more likely to experience CHF compared to younger individuals. Therefore, it can be expected that the feature "AGE" will have a higher range of values for patients with chronic heart failure compared to those without.

Based on this analysis, the dictionary with the appropriate values for the "AGE" feature can be generated as follows:

```json
{
    "no": [40.0, 45.0, 50.0, 55.0, 60.0],
    "yes": [65.0, 70.0, 75.0, 80.0, 85.0]
}
```

In this example, the values provided are just a representation of potential age values. The actual values should be determined based on the available data and the relationship between age and the task outcome.
