Based on prior knowledge, we can determine the appropriate ranges of serum cholesterol values that indicate whether a patient has heart disease or not. Typically, a serum cholesterol level below 200 mm/dl is considered normal, while levels above 240 mm/dl are considered high.

To analyze the relationship between the serum cholesterol feature and the presence of heart disease, we can divide the values into two categories:

1. Target class 'no': This category represents patients without heart disease.
Possible values of serum cholesterol for target class 'no' could be:
- 170.5
- 185.2
- 191.8
- 198.3
- 203.7

2. Target class 'yes': This category represents patients with heart disease.
Possible values of serum cholesterol for target class 'yes' could be:
- 250.9
- 267.4
- 280.1
- 298.6
- 310.2

Based on this analysis, the dictionary with the requested format would be:

```json
{
	"no": [170.5, 185.2, 191.8, 198.3, 203.7],
	"yes": [250.9, 267.4, 280.1, 298.6, 310.2]
}
```
