Suppose a study on the effects of meditation on stress levels found that participants who meditated for at least 20 minutes a day showed lower levels of cortisol, a stress hormone, compared to those who did not meditate. The study spanned over 6 months and included participants with varying levels of stress and anxiety.
Can we infer that "Meditating for at least 20 minutes a day will eliminate all stress in individuals"? Yes, no, or maybe?
