Based on prior knowledge, we can assume that the Recency feature represents the number of months since the person last donated blood. To analyze the relationship between the Recency feature and the task of whether the person donated blood, we can consider the following:

1. **Yes**: If the person donated blood, their Recency value is likely to be relatively low, indicating a recent donation. Typically, Recency values for the "yes" class may range from 0 to 6 months.

2. **No**: If the person did not donate blood, their Recency value is likely to be relatively high, indicating a longer duration since their last donation. Typically, Recency values for the "no" class may range from 7 to 50 months.

Based on this analysis, we can create the dictionary as follows:

```json
{
	"yes": [0.0, 2.0, 4.0, 5.0, 6.0],
	"no": [7.0, 9.0, 12.0, 20.0, 35.0]
}
```

Please note that the actual range and values for Recency may vary depending on the specific domain and dataset being analyzed.
