The Ball Corporation's beverage can manufacturing plant in Fort Atkinson, Wisconsin, uses a metal supplier that provides metal with a known thickness standard deviation σ = .000943 mm. Assume a random sample of 58 sheets of metal resulted in an x¯x¯ = .2603 mm. Calculate the 99 percent confidence interval for the true mean metal thickness. (Round your answers to 4 decimal places.) The 99% confidence interval is from blank to blank?
