Question: Two machines are used for filling plastic bottles with a met volume of 16.0 ounces. The filling processes can be assumed to be normal, with standard deviations of \(\sigma_{1}=0.015\) and \(\sigma_{2}=0.018\). The quality engineering department suspects that both machines fill to the same net volume, whether or not this volume is 16.0 ounces. An experiment is performed by taking a random sample from the output of each machine.

  1. State the hypotheses that should be tested in this experiment.
  2. Test these hypotheses using \(\alpha=0.05 .\) What are your conclusions?
  3. Find the \(P\) -value for this test.
  4. Find a 95 percent confidence interval on the difference in mean fill volume for the two machines.
