Based on prior knowledge, the relationship between age (AGE) and chronic heart failure can vary. In general, as people age, their risk of developing chronic heart failure increases. However, there is no specific age range that definitively determines whether a patient has chronic heart failure or not. 

To analyze the relationship between AGE and chronic heart failure in this scenario, we can consider typical age ranges for each target class. Here's the requested dictionary:

```json
{
  "no": [35.0, 45.0, 50.0, 55.0, 60.0],
  "yes": [65.0, 70.0, 75.0, 80.0, 85.0]
}
```

Please note that these values are only examples and the actual typical age ranges for each target class may vary depending on the specific dataset or research findings.
