Based on prior knowledge, we can analyze the relationship between the feature "Recency" (months since last donation) and the target variable "Did the person donate blood?"

Analysis of relationship:
- It is likely that people who donated blood more recently are more likely to donate again in the future.
- People who donated blood a long time ago may have forgotten or may not be interested in donating again.

Considering these observations, here is the dictionary with 5 typical Recency values for each target class:

```json
{
	"yes": [1.0, 2.0, 3.0, 4.0, 5.0], 
	"no": [12.0, 15.0, 18.0, 24.0, 30.0]
}
```

Please note that the values provided are just examples and may vary depending on the dataset and the specific task.
