Translate the statement into a confidence interval. Approximate the level of confidence.In a survey of 3327 adults in a country, 41% believe the economy is getting better. Three weeks prior to this survey, 59% believed that the economy was getting better. The survey's margin of error is ±1%.Use the results from the newer survey.The confidence interval for the proportion is ( D(Round to three decimal places as needed.)

Find an example of a confidence interval for a proportion in the media or scholarly literature (do not use a statistics textbook or website/article that is teaching or demonstrating statistics to find the example).At the very least it must include either the lower and upper bounds or a point estimate with a margin of error.Make sure you have a Proportion confidence interval and NOT a CI for the mean, odds ratio, hazard ratio, or relative risk as these will result in having to REDO the assignment(a) Include a digital photo/screenshot of the original appearance of the confidence interval and a link to the website (or citation) where it can be found. (b) Write the confidence interval in the form (lower bound, upper bound). If there are multiple confidence intervals, just pick one.
