Based on prior knowledge and without specific data, it is difficult to determine the appropriate ranges of values for the Insulin feature. However, it is generally known that insulin levels can vary depending on factors such as age, health condition, and lifestyle.

To proceed with the analysis, we assume that higher insulin levels may be associated with a higher likelihood of having diabetes. Keep in mind that further investigation with actual data is necessary to draw more accurate conclusions.

Here is a dictionary representing the relationship between the Insulin feature and the task, including 5 typical Insulin values for each target class:

```json
{
	"yes": [20.0, 25.8, 30.5, 35.2, 40.1],
	"no": [10.3, 12.7, 15.2, 18.6, 22.4]
}
```

Please note that these values are hypothetical and should not be considered as actual evidence of the relationship between Insulin and diabetes. It is essential to analyze real data to make more accurate conclusions.
