Based on prior knowledge, the relationship between the number of dependents (num_dependents) and whether a person receives credit can be analyzed as follows:

Analysis:
- It is likely that individuals with a higher number of dependents may have lower chances of receiving credit. This could be due to the increased financial responsibility and potential decrease in disposable income.
- Individuals with no dependents or a small number of dependents may have higher chances of receiving credit, as they may have more disposable income to fulfill their financial obligations.

Based on this analysis, the dictionary with the specific details will be as follows:

```json
{
	"yes": [0.0, 1.0, 2.0, 3.0, 4.0],
	"no": [1.0, 2.0, 3.0, 4.0, 5.0]
}
```

Note: The specific range of values for the "no" class may vary based on the dataset. The given values are just examples of typical num_dependents values for each target class.
