Based on prior knowledge and analysis, it is known that skin thickness can be an indicator of diabetes. Higher skin thickness is often associated with diabetes, as excess insulin in the body can lead to increased production of skin cells.

However, it is important to note that skin thickness alone cannot definitively determine the presence of diabetes. There are other factors involved, such as blood glucose levels, family history, and lifestyle choices, that play a significant role in the development of diabetes.

Based on this analysis, the dictionary with the specified format would be as follows:

```json
{
	"yes": [35.0, 40.0, 42.0, 46.0, 50.0],
	"no": [10.0, 15.0, 20.0, 25.0, 30.0]
}
```

In this dictionary, the "yes" class represents individuals with diabetes, while the "no" class represents individuals without diabetes. The list of floats within each class includes 5 typical skin thickness values for each group.
