To analyze the relationship between the Cholesterol feature and the presence of heart disease, we need to consider the typical ranges of cholesterol levels associated with heart disease.

Generally, elevated levels of serum cholesterol are considered a risk factor for heart disease. The range of values associated with heart disease varies, but typically total cholesterol levels above 240 mg/dL are considered high. However, it is important to note that the relationship between cholesterol levels and heart disease is not straightforward and can be influenced by various factors such as age, sex, and other medical conditions.

Based on this knowledge, we can proceed to create the dictionary with typical Cholesterol values for each target class:

```json
{
	"no": [150.5, 160.2, 155.8, 147.3, 170.1],
	"yes": [240.9, 255.6, 250.3, 265.1, 270.8]
}
```

Please note that these values are just examples and should not be considered as definitive thresholds for heart disease diagnosis. It is always important to consult with a medical professional for an accurate assessment.
