Question 18
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.
Question 19
Statement: 90% of students who attend all classes pass the exam. Sarah attended all classes.
What is the most reasonable conclusion?
Given the probabilistic nature of the statement, 'Sarah will likely pass the exam' is the most reasonable conclusion without overstating certainty.

Statement: Sarah passed the exam
Based only on the premises, is this statement:
Could be true — She meets the study requirement, but passing isn't guaranteed
