Column name "Total Charges" contains the token "total" which strongly signals real_additive. The numeric range [18.8, 8684.8] shows large unbounded magnitude centered far from both 0.0 and 1.0, consistent with an extensive absolute quantity (charges/costs). No zeros, strictly positive, high distinct fraction (92.9%) all support a cumulative financial measure where sum is the natural aggregation operation. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
