Share with us an article that refers to an example, application, or research of a confidence interval for 1 mean or 1 proportion. (You may also look at a confidence interval for a difference of means, difference of proportions, variances, but we did not cover those in this class due to time constraints.) In your post, provide a summary of the article and a complete explanation of the application and results given in your own words. Cite your reference, and provide a link to the article (if online). Provide the appropriate formula used to construct the confidence interval. If possible, try to reproduce the interval (sometimes articles don't provide enough information for this - in this case, you only need to mention the information they provide). If we increase the confidence for the interval found in your article, what would happen (stay the same / increase / decrease) to the standard error? margin of error? width of the interval?
