Final answer:
The research question for a study on a new glucose-based supplement is whether it improves energy levels and brain activity compared to a placebo. The hypothesis is that the supplement increases energy and cognitive performance. A randomized controlled trial with double-blind procedures would be used for testing.
Step-by-step explanation:
To test the effectiveness of a new supplement aimed at boosting energy levels by enhancing brain activity with natural glucose, an appropriate research question could be, 'Does the intake of the new glucose-based supplement improve energy levels and brain activity compared to a placebo?'The hypothesis for this study might be, 'Participants who take the new glucose-based supplement will demonstrate higher energy levels and increased cognitive performance in comparison to those who take a placebo.'
The experimental setup would involve a randomized controlled trial where participants are randomly assigned to either the experimental group or the control group. The experimental group would receive the actual supplement, while the control group would receive a placebo without active ingredients. Both groups' energy levels and cognitive performance would be measured using standardized assessments before and after the supplementation period to determine the supplement's effect.
To ensure the power of suggestion does not influence the outcome, a double-blind approach should be used where neither the participants nor the researchers know who belongs to which group until the study is completed. This setup helps in avoiding biases that could affect the results from the expectation of the participant or the observer.
