A Confidence Interval in the News and Medical Journals

In everyday terms, a confidence interval is the range of values around a sample statistic (such as mean or proportion) within which clinicians can expect to get the same results if they repeat the study protocol or intervention, including measuring the same outcomes in the same ways. Find an example of a confidence interval in the news, scholarly source, or medical journal.

Summarize the article/study. Does the article/study include the sample size and the level of confidence used to create the confidence interval? Explain what the confidence interval means in the context of the news article or scholarly source. How do you think the confidence interval that was presented in the study was calculated?
