<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A randomized control double-blind study is conducted on the efficacy of 2 sulfonylureas. The study concluded that medication 1 was more efficacious in lowering fasting blood glucose than medication 2 p 0.05; 95 CI: 14 10-21. Which of the following is true regarding a 95 confidence interval CI?? A: It represents the probability that chance would not produce the difference shown, 95 of the time., B: When a 95 CI for the estimated difference between groups contains the value 0, the results are significant., C: The range of outcome values resulting from the trial has a 95 probability of encompassing the true value., D: The study is adequately powered at the 95 confidence interval., E: The 95 confidence interval is the probability chosen by the researcher to be the threshold of statistical significance.,  <response>: This is a question about interpreting the results and meaning of a 95 confidence interval from a randomized controlled trial comparing two medications. The key things to analyze are:- This is a randomized controlled double-blind study, which is a high quality experimental design to compare two treatments. - They found a statistically significant difference in lowering fasting blood glucose between the two medications p0.05. - The results are reported with a 95 confidence interval of the difference between groups.- The choices discuss concepts like statistical significance, study power, probability that the results occurred by chance, and the interpretation of the confidence interval.C: The range of outcome values resulting from the trial has a 95 probability of encompassing the true value.
