Based on prior knowledge, the maximum heart rate achieved (MaxHR) can provide some insights into the presence of heart disease. Typically, a higher maximum heart rate is associated with a healthier cardiovascular system, while a lower maximum heart rate can indicate the presence of heart disease.

To create the desired dictionary, I will analyze the relationship between the MaxHR feature and the presence of heart disease, and then provide five typical MaxHR values for each target class ('no', indicating absence of heart disease, and 'yes', indicating presence of heart disease).

```json
{
  "no": [180.0, 175.0, 185.0, 170.0, 176.0],
  "yes": [145.0, 152.0, 158.0, 149.0, 136.0]
}
```

Please note that these values are hypothetical and may not represent actual medical data. They are provided here to demonstrate the format of the dictionary.
