Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Compare conditional frequencies for the same outcome across groups.
2. If they are equal or nearly equal, variables appear independent.
3. If they differ meaningfully, variables are associated.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Basing independence on equal row totals.
