Walkthrough
Full solution stays hidden until you ask for it.
1. Build interval for each estimate.
2. Compare overlap or separation.
3. State whether evidence suggests a meaningful difference.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Comparing point estimates alone when margins are given.
