Suppose a study was conducted on the effects of mindfulness meditation on stress levels in college students. The researchers recruited 100 participants and divided them into two groups: one group practiced mindfulness meditation for 20 minutes daily, while the other group did not. After 6 weeks, stress levels were measured using a standardized questionnaire. The results showed a statistically significant decrease in stress levels among the group that practiced mindfulness meditation.
Can we infer that "Mindfulness meditation had no impact on stress levels in college students."? Yes, no, or maybe?
