To analyze the relationship between the RestingBP feature and the presence of heart disease (target variable), we can use our prior knowledge to determine appropriate ranges of values for RestingBP.

As RestingBP represents resting blood pressure in mm Hg, values between 90 and 120 mm Hg are considered normal for adults. RestingBP values above 120 mm Hg are generally considered high and may indicate hypertension or other cardiovascular concerns.

Based on this information, we can create a dictionary as follows:

```json
{
    "no": [100.0, 105.0, 110.0, 115.0, 120.0],
    "yes": [130.0, 135.0, 140.0, 145.0, 150.0]
}
```

In the dictionary above, we include 5 typical RestingBP values for each target class. For the "no" class, representing patients without heart disease, we consider RestingBP values between 100 mm Hg and 120 mm Hg. For the "yes" class, representing patients with heart disease, we consider RestingBP values above 120 mm Hg, ranging from 130 mm Hg to 150 mm Hg.

Please note that these ranges and values are generalizations and should be considered in the context of specific clinical guidelines and recommendations.
