Full solution stays hidden until you ask for it.
1. Recall that correlation coefficient r ranges from -1 to 1 inclusive.
2. Compare the given value with that interval.
3. State whether it is possible and why.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Treating percentages such as 120% as valid r-values.
