Walkthrough
Full solution stays hidden until you ask for it.
1. Identify estimate and margin of error in matching units.
2. Subtract margin for lower bound and add for upper bound.
3. Interpret interval as plausible population proportion range.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Multiplying estimate by margin of error.
