Based on prior knowledge, the relationship between age and chronic heart failure can be analyzed as follows:

1. It is generally known that the risk of developing chronic heart failure increases with age. Older individuals are more likely to experience heart-related complications.
2. Different age ranges might have varying levels of risk for chronic heart failure. For example, individuals in their 40s may have a lower risk compared to those in their 70s or 80s.

With this understanding, we can analyze the data and create the requested dictionary:

```json
{
	"no": [30.5, 32.1, 34.8, 36.7, 39.2],
	"yes": [72.3, 76.5, 78.9, 81.2, 85.7]
}
```

In this example, we have provided five typical AGE values for each target class. The "no" class represents patients without chronic heart failure, while the "yes" class represents patients with chronic heart failure. Please note that the provided values are just fictional examples and should be updated with actual data once available.
