A reseаrch study wаs cоnducted оn а new supplement called "Instant Energy". The randоmized controlled trial had 2000 participants (1000 were randomized to the control group and 1000 to the intervention group). The intervention group received the treatment over 12 weeks while the control group received placebo over the same time frame. All participants completed the Fatigue Numeric Rating Scale before and after the treatment period. The Fatigue Numeric Rating Scale was selected because previous researchers reported strong reliability and validity data. In previous reports, researchers learned that a 3 point change in fatigue score was necessary to demonstrate a clinically meaningful improvement.  Post treatment results  Control group - mean scores post intervention scores demonstrated 1.2 point increase Intervention group - mean scores post intervention demonstrated 1.6 point increase. The differences between the two groups were found to be statistically significant p < .042 Would you recommend this supplement to tired students and faculty? (1 point) Why or Why not? (2 points)
