Based on prior knowledge, the relationship between age and the presence of chronic heart failure (CHF) can be analyzed. Generally, as the age increases, the risk of developing CHF also increases. However, it is important to note that age alone may not be a definitive predictor of CHF as it can also be influenced by other factors.

Here is the analysis and dictionary for the given feature and task:

```json
{
	"no": [30.5, 35.2, 40.7, 45.8, 50.2],  
	"yes": [60.1, 65.3, 70.6, 75.2, 80.4]  
}
```

In this dictionary, the "no" key represents the possible values of the feature AGE for patients without chronic heart failure, and the "yes" key represents the possible values of the feature AGE for patients with chronic heart failure. The values provided are typical age values for each target class. Note that these values are just examples and may not be specific to the given dataset.
