Based on prior knowledge, the installment_commitment is the percentage of disposable income dedicated to paying installments. A higher installment_commitment value indicates a higher proportion of income being used to pay installments.

To analyze the relationship between installment_commitment and the task of whether a person receives credit or not, we can make some assumptions:

1. If the installment_commitment is low, i.e., a small percentage of disposable income is used for paying installments, it may indicate that the person has a good financial position and is more likely to receive credit.
2. On the other hand, if the installment_commitment is high, i.e., a large percentage of disposable income is used for paying installments, it may indicate a higher financial risk, resulting in a lower chance of receiving credit.

Based on these assumptions, let's create the dictionary:

```json
{
	"yes": [10.0, 15.0, 20.0, 25.0, 30.0],
	"no": [40.0, 45.0, 50.0, 55.0, 60.0]
}
```

In this dictionary, the "yes" class includes typical installment_commitment values of 10.0, 15.0, 20.0, 25.0, and 30.0. These values are relatively low, indicating a higher chance of receiving credit. Conversely, the "no" class includes typical installment_commitment values of 40.0, 45.0, 50.0, 55.0, and 60.0. These values are relatively high, indicating a lower chance of receiving credit.
