Based on my prior knowledge, I can analyze the relationship between the Cholesterol feature and the presence of heart disease. Typically, higher levels of serum cholesterol are associated with an increased risk of heart disease. The specific ranges of values for determining the appropriate cholesterol levels may vary depending on the reference ranges used in different medical contexts. 

To create the dictionary, I need to find typical cholesterol values for both target classes ('no' and 'yes').

Here is the dictionary:

```json
{
    "no": [150.0, 160.0, 170.0, 180.0, 190.0],
    "yes": [200.0, 210.0, 220.0, 230.0, 240.0]
}
```
Please note that these values are just examples and may not be accurate for real-world scenarios. Actual ranges and typical values should be determined based on medical guidelines and reference ranges specific to the dataset being analyzed.
