Based on the given feature "LBXGLT" and the task to predict the person's age group (either Senior or non-Senior), it seems that LBXGLT is a numeric variable that might be related to age. However, since no specific details about the feature or its values are provided, I will rely on my prior knowledge to determine the appropriate ranges and analyze the relationship.

Here is the dictionary containing the possible values of feature LBXGLT for each target class:

```json
{
	"Adult": [33.5, 38.2, 39.1, 41.7, 45.9],
	"Senior": [47.3, 51.8, 56.2, 58.7, 63.4]
}
```

Please note that these values are just examples based on a hypothetical scenario. The actual values and ranges may vary depending on the dataset and the context.
