Publishes data on the hourly compensation for production workers in manufacturing sector of the economy. The latest figures published by this government agency show that the average hourly wage for a production worker in manufacturing is $14.55. To examine the consistency of this figure, a random sample of 25 production workers in manufacturing from the across the county is selected and based on this sample it has been determined that the standard deviation of hourly wages for such workers is $1.12. Use this information to develop a 95% confidence interval to estimate the production variance for the hourly wages of production workers in U.S. What is the value of upper limit of this confidence interval?
