To analyze the relationship between the feature "Insulin" and the task of determining whether a person has diabetes or not, I will consider the typical ranges of values for serum insulin levels in individuals with and without diabetes.

Based on prior knowledge, here are the followings ranges of insulin values:

Normal Range:
- Fasting: 5-15 mu U/ml
- Post-meal: up to 25 mu U/ml

Diabetes Range:
- Fasting: above 15 mu U/ml
- Post-meal: above 25 mu U/ml

Now, I will create a dictionary with the possible Insulin values for each target class:

```json
{
	"yes": [25.2, 22.5, 30.1, 27.8, 35.6],
	"no": [10.3, 8.9, 12.6, 11.8, 9.7]
}
```

Please note that these values are just examples and not representative of the entire dataset or population. The dictionary provides approximate values that are typically seen in individuals with and without diabetes for the feature "Insulin".
