Based on prior knowledge and analysis, the num_dependents feature likely has an impact on determining whether a person receives credit or not. Typically, as the number of dependents increases, the likelihood of receiving credit may decrease due to increased financial responsibility and potentially higher risk.

Here is the dictionary containing the typical num_dependents values for the 'yes' and 'no' target classes:

```json
{
	"yes": [0.0, 1.0, 2.0, 3.0, 4.0],
	"no": [0.0, 1.0, 2.0, 3.0, 4.0]
}
```

Please note that the specific range of num_dependents values and their impact may vary depending on the dataset and context. The provided values are just examples of what could be considered typical for the given task.
