Based on prior knowledge, the installment_commitment feature represents the percentage of disposable income committed to installment payments. To understand its relationship with the target variable of whether a person receives credit, we can analyze the average installment_commitment values for the two target classes.

Here is the analysis of the relationship between the installment_commitment feature and the task of whether a person receives credit:

1. For the 'yes' class (person receives credit), typical installment_commitment values could be:
   - 10.0
   - 15.0
   - 20.0
   - 25.0
   - 30.0

2. For the 'no' class (person does not receive credit), typical installment_commitment values could be:
   - 35.0
   - 40.0
   - 45.0
   - 50.0
   - 55.0

Based on this analysis, we can create the dictionary as follows:

```json
{
	"yes": [10.0, 15.0, 20.0, 25.0, 30.0],
	"no": [35.0, 40.0, 45.0, 50.0, 55.0]
}
```
