Premise: The French postal density is higher at every quantile, but the ratio is strikingly high at the 95th and 90th quantiles where it exceeds 3 to 1. On average the French postal density exceeds the U.S. by a ratio of 2.5 to 1. This is somewhat less than the ratio of population density between France and the U.S. which is 3.6 to 1.10

Hypothesis: France has a lower population density than the U.S.
Relation: contradiction
