Suppose a new study from Harvard University has found that students who get at least 8 hours of sleep per night perform better academically than those who do not. The research indicates that sleep plays a crucial role in cognitive function and memory consolidation. The study also suggests that implementing later school start times could improve student performance across the board.
Can we infer that "Students who sleep less than 8 hours per night excel academically."? Yes, no, or maybe?
