Based on prior knowledge, we can analyze the relationship between the feature "Time" (months since first donation) and the task of determining whether the person donated blood or not.

Usually, a higher value of "Time" indicates that the person has donated blood multiple times in the past, while a lower value indicates that the person has donated blood fewer times or it has been a longer time since the first donation.

Based on this analysis, we can create a dictionary with typical values of "Time" for each target class:

```json
{
	"yes": [2.0, 4.0, 6.0, 8.0, 10.0],  
	"no": [0.0, 1.0, 3.0, 5.0, 7.0]  
}
```

These values represent typical examples and may not cover the entire range of possible values.
