Question
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 \( \sigma = 0.000619 \) mm. Assume a random sample of 46 sheets of metal resulted in an \( \overline{x} = 1903 \) 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 [ ] to [ ].
