Explanation:
Based on prior knowledge, heart diseases tend to be more prevalent in older individuals. Therefore, it is reasonable to assume that patients with heart disease will generally have a higher age compared to those without heart disease.

For the target class "no" (patients without heart disease), typical age values could range from 40 to 55 years old. These values are chosen to represent a relatively younger population without heart disease.

For the target class "yes" (patients with heart disease), typical age values could range from 60 to 75 years old. These values are chosen to represent an older population with a higher likelihood of having heart disease.
