Suppose A new study from the University of California found that students who eat a healthy breakfast perform better in school. The study surveyed 500 students from different schools across the state and analyzed their breakfast habits and academic performance over a six-month period. The results showed a clear correlation between eating a nutritious breakfast and scoring higher grades on exams and assignments. Researchers suggest that schools should implement breakfast programs to ensure all students have access to a healthy meal before starting their day.
Can we infer that "All 500 students surveyed in the study ate a healthy breakfast every day"? Yes, no, or maybe?
