Suppose a recent study conducted by a team of psychologists found that people who spend more time outdoors tend to report lower levels of stress and anxiety. The study surveyed participants from different age groups and backgrounds, measuring their exposure to nature and mental well-being. The researchers concluded that spending time in nature can have a positive impact on mental health.
Can we infer that "Everyone who participated in the study reported lower levels of stress and anxiety"? Yes, no, or maybe?
