To analyze the relationship between the feature "Recency" and the task of whether the person donated blood or not, we can examine the typical values of "Recency" for each target class.

Based on prior knowledge in blood donation, it is common for people to donate blood every 2-3 months. Therefore, we can consider the following ranges for the "Recency" values:

- 0 to 2: indicates recent donations
- 3 to 5: indicates donations within the past few months
- 6 to 8: indicates donations within the past 6 to 8 months
- 9 to 11: indicates donations within the past 9 to 11 months
- 12 or more: indicates donations made a year or more ago

Using these ranges, we can generate the dictionary:

```json
{
	"yes": [0.0, 1.0, 2.0, 3.0, 4.0],
	"no": [6.0, 7.0, 9.0, 11.0, 12.0]
}
```

Please note that the values provided are just examples and may vary based on the specific dataset and the distribution of the "Recency" variable.
