Based on prior knowledge, the resting electrocardiogram (RestingECG) can provide valuable information about the presence of heart disease. Here is an analysis of the relationship between the RestingECG feature and the target variable (coronary angiography showing heart disease) for the given task:

- Normal RestingECG: It is most likely that patients with a normal resting electrocardiogram would not show signs of heart disease on coronary angiography. Therefore, the target class 'no' is more likely to have Normal RestingECG.

- ST RestingECG: ST changes on electrocardiogram can indicate myocardial ischemia or injury. These changes may suggest possible heart disease, so it is possible to see both 'yes' and 'no' in the target class for ST RestingECG.

- LVH RestingECG: Left ventricular hypertrophy (LVH) is associated with increased risk of heart disease. Patients with LVH on electrocardiogram are more likely to show heart disease on angiography. Thus, the target class 'yes' is more likely to have LVH RestingECG.

Based on this analysis, the dictionary with the specific details can be as follows:

```json
{
	"no": ["Normal"],
	"yes": ["LVH", "ST"]
}
```

The possible values of the RestingECG feature that are associated with the target class 'no' are "Normal". The possible values of the RestingECG feature associated with the target class 'yes' are "LVH" and "ST".
