Based on prior knowledge, I will analyze the relationship between the credit_amount feature and the task of determining whether a person receives credit or not. 

Typically, the credit amount is an important factor in determining whether a person receives credit or not. Higher credit amounts may indicate that the person has a higher capacity to repay the loan and hence more likely to receive credit. Conversely, lower credit amounts may indicate higher risk and lower chances of receiving credit.

Here's the dictionary with the specific details you requested:

```json
{
	"yes": [1000.0, 2000.0, 3000.0, 4000.0, 5000.0],
	"no": [500.0, 100.0, 200.0, 300.0, 400.0]
}
```

Please note that these values are just hypothetical examples and may not accurately represent the actual relationship between credit_amount and credit approval.
