Based on my prior knowledge and analysis of the relationship between ALT_BLOOD and the presence of chronic heart failure, I have determined the appropriate ranges of values for this feature.

To build the dictionary, I will use the following steps:

1. Identify the typical ALT_BLOOD values for the target class 'no' (indicating no chronic heart failure).
2. Identify the typical ALT_BLOOD values for the target class 'yes' (indicating chronic heart failure).
3. Build the dictionary with the identified values.

Here is the dictionary with the required format:

```json
{
	"no": [10.5, 15.2, 19.7, 21.3, 24.8],
	"yes": [26.5, 28.1, 31.4, 35.2, 39.6]
}
```

In this example, I have included 5 typical ALT_BLOOD values for each target class ('no' and 'yes'). These values are represented as floats in the lists. Please note that the specific values provided are just examples and can vary depending on the actual dataset and analysis.
