```json
{
	"yes": ["none"],  
	"no": ["bank", "stores"]
}
```
Explanation:

Upon analyzing the relationship between the feature "other_payment_plans" and the task of whether the person receives credit, we can observe the following:

1. For individuals who receive credit (target class "yes"), the only known value for the feature "other_payment_plans" is "none".
2. For individuals who do not receive credit (target class "no"), there are two known values for the feature "other_payment_plans": "bank" and "stores".

Based on this analysis, we can create a dictionary with the known values of the feature for each target class as shown above.
