Answer :
Final answer:
For correlated variables, a cause-effect relationship may not exist; factors like study habits can lead to misleading correlations.
Explanation:
Variables A and B do not appear to share a cause-effect relationship when there is a correlation present. In the context of the given pairs:
- Shoe size and ratings for a radio show are unlikely to have a cause-effect relationship as they are unrelated factors.
- Japan's stock market performance and hours of television watched per day might not be causally linked as one does not directly impact the other.
- Hours of television watched per day and performance in school may have a correlation due to a common cause like study habits but not a direct cause-effect relationship.
