Based on prior knowledge, the relationship between serum cholesterol levels and the presence of heart disease can be assessed. Typically, higher levels of serum cholesterol tend to increase the likelihood of heart disease.

To generate the dictionary with specific details, we will consider five typical cholesterol values for each target class:

Cholesterol values for target class 'no':
- 160.5
- 180.2
- 155.8
- 170.3
- 175.7

Cholesterol values for target class 'yes':
- 220.1
- 240.6
- 215.9
- 230.4
- 210.7

The dictionary will have the following format:

```json
{
	"no": [160.5, 180.2, 155.8, 170.3, 175.7],
	"yes": [220.1, 240.6, 215.9, 230.4, 210.7]
}
```
