Based on prior knowledge, the number of dependents can potentially have an influence on whether a person receives a credit or not. Here is the analysis of the relationship between the feature "num_dependents" and the task of whether the person receives a credit or not:

- Yes: A person with a higher number of dependents may have a higher likelihood of receiving a credit, as they may have more financial responsibilities and expenses to support.

- No: On the other hand, a person with a lower number of dependents may have a higher likelihood of not receiving a credit, as they may have fewer financial responsibilities and expenses to support, indicating a potentially higher creditworthiness.

Based on this analysis, here is the dictionary with the possible values of the feature "num_dependents" for each target class:

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