A study is conducted in order to find a 95% confidence interval for the mean water bill for households in a city. From a sample of 83 households, the mean bill was found to be $49.67. Assume it is known that the population standard deviation is $3.93. Find the confidence interval. This answer will have two values. report only the larger of the two values as your answer.

Round your answer to two decimal places and do not include the $ sign (For example: 77.54)

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...
