onfidence Intervals for One Population Mean he following requirements must be met for this discussion board: ind a credible journal article or website where confidence intervals were used to make informed decisions regarding a real-world application. I don't ant a textbook-like application. These intervals must have been determined within the context of a documented and citable research study. The whole point of this discussion is to perform an analysis of real-world data within the context of this week's lesson topics. Identify and provide me with access to your source. Upload a pdf or html file containing a peer-reviewed and scholarly journal article (e.g., The Ne England Journal of Medicine) or provide the URL to a credible website (e.g., https:/ces.ed.gov/).

You need to provide me with a file containing your arti f you want any credit for your main discussion response. No file, no credit for your main discussion post. What was the research question that was under investigation? State the actual question. 3. State the ways in which the assumptions for using a confidence interval were met. State whether the population standard deviation is known or not known. 4. Report at least FOUR specific confidence interval results from the cited study. . o State each interval [ (34.7, 44.7) ] o What was the level of confidence for each interval (e.g., 95%). 5. For each of your FOUR reported specific confidence intervals, interpret these results within the context of how they help to address the research question that was posed. In what ways can these results be used to make informed decisions regarding the phenomenon under study. this week's discussion
