The ABC Electric Motor Company provides the motors for Company XYZ s conveyor belts.
Company XYZ has asked the ABC Electric Motor Company to determine the failure rate for the
motors supplied. ABC Electric Motor Company designed an experiment where 11 motors were
ran continuously for 8000 hours or until failure. Of the 11 motors that were tested, only 1 failed
at 4270 hours. The remaining 10 motors were operational throughout the experiment. When
the motor failed it was not replaced. Determine the failure rate. - Answers .0000119
