Based on prior knowledge, the level of insulin in the blood can be an important factor in determining whether a person has diabetes or not. Insulin is a hormone that helps regulate blood sugar levels, and people with diabetes often have irregular levels of insulin.

To analyze the relationship between insulin and the task of determining if a person has diabetes, we can look at typical ranges of insulin values for people with and without diabetes.

Here's a dictionary with typical insulin values for each target class:

```json
{
	"yes": [50.0, 60.0, 70.0, 80.0, 90.0], 
	"no": [5.0, 10.0, 15.0, 20.0, 25.0]
}
```

In this example, we assume that higher insulin values are indicative of diabetes ("yes" class) and lower insulin values are indicative of not having diabetes ("no" class). The values presented are just examples and could vary depending on the dataset and specific context.

Please note that this analysis is based on prior knowledge and typical patterns, and further analysis with actual data would be required to confirm the relationship between insulin levels and the task of determining if a person has diabetes.
