Analysis:

To determine the relationship between the feature ALT_BLOOD and the presence of chronic heart failure, we can analyze the typical values of ALT_BLOOD for patients with and without chronic heart failure.

Based on prior knowledge, the range of normal ALT_BLOOD values is generally between 10 to 40 units per liter. Higher values can indicate liver disease or damage.

As there is no specific information given about the ranges of ALT_BLOOD values that can indicate chronic heart failure, we will assume that higher values might be associated with chronic heart failure. However, it is important to note that this assumption may not be universally applicable and could vary depending on the specific dataset and population.

Based on this assumption, we can create a dictionary to summarize the typical ALT_BLOOD values for the target classes 'no' and 'yes':

```json
{
    "no": [15.2, 21.9, 18.5, 28.7, 13.6],
    "yes": [31.4, 26.8, 23.2, 35.6, 29.1]
}
```

Please note that the values provided above are just fictional examples for illustration purposes and may not reflect actual data. The values should be determined based on the dataset and domain knowledge when performing a real analysis.
