Based on prior knowledge, the Body Mass Index (BMI) is a commonly used measure to assess if a person is underweight, normal weight, overweight, or obese. The range of BMI values associated with diabetes may vary, but generally, higher BMI values are associated with an increased risk of developing diabetes.

For the task "Does this person have diabetes?", we can analyze the relationship between BMI and the target variable. Based on this analysis, we can create the requested dictionary as follows:

```json
{
	"yes": [28.4, 30.8, 33.2, 35.7, 37.9],
	"no": [22.1, 23.9, 25.5, 26.8, 27.6]
}
```

The above dictionary provides 5 typical BMI values for each target class ('yes' and 'no'). These values are meant to represent possible BMI ranges associated with the target class.

Please note that the provided values are just for example purposes and should be adjusted based on relevant research or data analysis specific to the dataset being used.
