Based on prior knowledge, the feature "Recency" represents the number of months since the last blood donation. To analyze its relationship with the target variable, "Did the person donate blood? (Yes or no)," we can consider the following:

1. Individuals who donated blood more recently are more likely to donate again in the future. Therefore, for the target class "yes," we would expect to see lower recency values, indicating recently donated blood.

2. Individuals who haven't donated blood in a long time may be less likely to donate again. Hence, for the target class "no," we would expect to observe higher recency values, indicating a longer duration since their last donation.

To create the requested dictionary with specific Recency values for each target class, we will include five typical values for both "yes" and "no" classes:

```json
{
  "yes": [0.3, 0.2, 1.5, 0.1, 0.8],
  "no": [25.0, 15.6, 30.2, 17.8, 21.9]
}
```
Please note that these values are just examples and may not reflect the actual dataset. The specific values would depend on the characteristics of the dataset being analyzed.
