To analyze the relationship between the feature LBXGLU and the target age group, we can consider the typical ranges of blood glucose levels for different age groups.

Based on general medical knowledge, the normal blood glucose range for fasting individuals is typically between 70 and 99 mg/dL. However, it is important to note that blood glucose levels can vary based on various factors such as age, health condition, and other individual factors.

For the purpose of this analysis, we can assume the following ranges to classify the age groups:
- Adult: LBXGLU between 70 and 140 mg/dL (typical range for non-diabetic adults).
- Senior: LBXGLU above 140 mg/dL (potential indicator of impaired glucose tolerance or diabetes in older individuals).

Using these ranges, we can generate a dictionary with the typical LBXGLU values for each age group:

```json
{
	"Adult": [90.5, 95.2, 103.1, 110.6, 128.3],
	"Senior": [150.9, 162.4, 170.8, 185.7, 195.2]
}
```

Please note that these values are just examples and may not reflect the true distribution of the LBXGLU feature in the given dataset.
