Based on prior knowledge, there are generally accepted ranges for serum cholesterol levels that indicate different risk levels for heart disease. 

Here's an analysis of the relationship between serum cholesterol levels and the presence of heart disease:

1. Typically, a serum cholesterol level below 200 mg/dl is considered normal or low risk for heart disease.
2. Serum cholesterol levels between 200 and 239 mg/dl are considered borderline high risk.
3. Levels between 240 and 279 mg/dl are considered high risk.
4. Levels of 280 mg/dl and above are considered very high risk.

Using this information, we can create the desired dictionary that includes typical cholesterol values for each target class:

```json
{
	"no": [150.0, 180.0, 190.0, 195.0, 198.0],
	"yes": [250.0, 260.0, 270.0, 290.0, 310.0]
}
```

Please note that the exact ranges and typical values can vary depending on specific medical guidelines and research findings. It is always recommended to consult with medical professionals for accurate interpretation and diagnosis.
