Based on prior knowledge, it is known that high levels of serum cholesterol are associated with an increased risk of heart disease. Although there is no specific range to determine whether a patient has heart disease based solely on their cholesterol levels, there are general guidelines for assessing risk.

Analysis of the relationship between Cholesterol and heart disease:

- Typically, cholesterol levels below 200 mg/dl are considered desirable.
- Cholesterol levels between 200 and 239 mg/dl are considered borderline high.
- Cholesterol levels above 240 mg/dl are considered high.

As the task is to determine if the coronary angiography shows heart disease, we can assume that higher cholesterol levels indicate a higher likelihood of heart disease.

Dictionary analysis:

```json
{
	"no": [150.5, 175.2, 165.8, 185.3, 170.6],
	"yes": [210.1, 225.8, 240.7, 285.4, 255.2]
}
```

In the above dictionary, the "no" key corresponds to the possible cholesterol values for patients who do not show heart disease, and the "yes" key corresponds to the possible cholesterol values for patients who do show heart disease. The values for each key are example cholesterol levels specific to each target class.
