A metal lathe is checked periodically by quality-control inspectors to determine whether it is producing machine bearings
Question:
A metal lathe is checked periodically by quality-control inspectors to determine whether it is producing machine bearings with a mean diameter of .5 inch. If the mean diameter of the bearings is larger or smaller than .5 inch, then the process is out of control and must be adjusted. Formulate the null and alternative hypotheses for a test to determine whether the bearing production process is out of control.
