Net interstate balance
Colorado recorded 24,205 more departures to other states than arrivals from them (difference ± 17,168, 90% MOE). That balance is larger than its own margin of error, so the direction is distinguishable from zero at 90% confidence.
Difference test: √(MOE_in² + MOE_out²) per Census Bureau statistical-testing guidance. Not a net count of trucks or shipments.
