Based on prior knowledge, there might be some relationship between skin thickness and diabetes. Higher skin thickness may be associated with a higher risk of diabetes. Let's analyze the relationship between the feature "SkinThickness" and the target variable "Does this person have diabetes?". 

To create the dictionary, I will need a dataset that includes the feature "SkinThickness" and the corresponding target variable "Does this person have diabetes?" for a given set of individuals. Unfortunately, I do not have access to such a dataset. Hence, I cannot provide the exact dictionary values.

However, I can provide a template of the desired dictionary with typical values for the target classes "yes" and "no" as requested:

```json
{
	"yes": [25.0, 30.0, 40.0, 35.0, 28.0],
	"no": [20.0, 18.0, 22.0, 15.0, 19.0]
}
```

Please note that the above values are just hypothetical and do not represent any real data. To obtain accurate values, an analysis using an appropriate dataset is required.
