Based on prior knowledge, serum cholesterol levels are often used as a risk factor for heart disease. Higher cholesterol levels are associated with a higher risk of heart disease. 

To analyze the relationship between cholesterol levels and the presence of heart disease, we can look at typical values for cholesterol in each target class ('no' and 'yes').

Here is the dictionary with the specified format:

```json
{
	"no": [140.0, 160.0, 180.0, 200.0, 220.0],
	"yes": [220.0, 240.0, 260.0, 280.0, 300.0]
}
```

Please note that the values provided in the dictionary are example values and may not reflect the actual typical values for cholesterol levels in each target class.
