Based on prior knowledge, we can determine the appropriate ranges of BMXBMI values for different age groups. Since the task is to predict whether a person belongs to the "Senior" or "Non-Senior" age group, we can classify "Senior" as those individuals who are aged 65 or older.

To analyze the relationship between BMXBMI and the age group, we need to examine typical BMXBMI values for each age group. Here is an analysis of five typical BMXBMI values for the "Adult" and "Senior" age groups:

- Adult: BMXBMI in the range of 18.5 to 24.9 is considered normal weight. Therefore, typical BMXBMI values for the adult age group could be [20.0, 22.3, 21.1, 23.7, 24.5] (all within the normal weight range).
- Senior: As people age, a slightly higher BMI might be considered healthy. BMXBMI in the range of 25.0 to 29.9 is classified as overweight. Therefore, typical BMXBMI values for the senior age group could be [26.5, 28.2, 27.7, 29.1, 26.8] (all within the overweight range).

Based on this analysis, the dictionary with the typical BMXBMI values for each age group would look like this:

```json
{
	"Adult": [20.0, 22.3, 21.1, 23.7, 24.5],
	"Senior": [26.5, 28.2, 27.7, 29.1, 26.8]
}
