Based on prior knowledge, we can assume that the feature "Monetary" (total blood donated in c.c.) would likely have a positive relationship with the target variable "Did the person donate blood?". If a person has donated blood in the past, it is likely that they have a higher value for the "Monetary" feature compared to someone who has not donated blood.

Here is a dictionary that includes 5 typical monetary values for each target class:

```json
{
	"yes": [350.0, 500.0, 650.0, 800.0, 950.0],
	"no": [100.0, 150.0, 200.0, 250.0, 300.0]
}
```
Please note that the monetary values are arbitrary and should be adjusted based on the specific context and data available.
