Based on prior knowledge, the level of insulin in the blood can be an important indicator of whether a person has diabetes or not. Higher levels of insulin can indicate insulin resistance and may be associated with diabetes.

Here is the dictionary with the relevant information:

```json
{
    "yes": [180.0, 200.0, 220.0, 240.0, 250.0],
    "no": [50.0, 60.0, 70.0, 80.0, 90.0]
}
```

For the target class "yes" (indicating the person has diabetes), some typical Insulin values could be 180.0, 200.0, 220.0, 240.0, and 250.0 (in mu U/ml).

For the target class "no" (indicating the person does not have diabetes), some typical Insulin values could be 50.0, 60.0, 70.0, 80.0, and 90.0 (in mu U/ml).

However, it's important to note that further analysis and validation using actual data should be conducted to confirm the relationship between Insulin levels and diabetes.
