Question

A federal inspector visited an oil refinery for a routine

inspection. He used a 99% confidence interval to estimate
the true mean amount of sulfur contained in the fuel oil
made by the refinery. His confidence interval was (1.91,
2.29). Which of the following is the best way to report or
interpret this confidence interval?

Answer 1

We are 99% confident that the interval from 1.91 to 2.29 (units of sulfur) captures the true mean amount of sulfur contained in the fuel made by the refinery.
