A research study was conducted on a new supplement called “Instant Energy”. The randomized 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)

The purpose of this study was to quantify relationships between academic achievement (GPA) and nutrition. Students completed a Likert-type dietary survey. The survey was designed to capture the amounts/types of foods consumed and numerically qualify the dietary components. Then the results were statistically compared to GPA. Using the table below identify all reported measures that had a statistically significant relationship with GPA. (Full points will be awarded if you correctly list each statistically significant variable. 1 point will be deducted for each variable listed that was not statistically significant.) Total score is considered a variable. Variable Test statistic P-value Total score 0.017 0.030 Vegetables 0.040 0.011 Fruits 0.050 0.029 Meats -0.048 0.242 Non-meat protein 0.075 0.061 Breads and cereals 0.055 0.049 Dairy 0.024 0.466 Water 0.196 0.041 Spreads and sauces -0.149 0.486
