Question 1
Premises: In a study of 10,000 people, 95% who exercised daily reported better sleep. 80% who exercised 3-4 times weekly reported better sleep. 30% who exercised rarely reported better sleep. Sarah exercises 5 times per week.
1. Sarah definitely has better sleep than someone who never exercises
2. Sarah is more likely to have better sleep than the average person
3. Exercise improves sleep quality for most people
Which conclusion is the WEAKEST (most/least strongly supported by the premises)?
The weakest conclusion is: 'Sarah definitely has better sleep than someone who never exercises' because Correlation doesn't guarantee individual outcomes; individual variation exists.
