Answer: the more likely this machine will be a candidate for preventative maintenance.
Explanation: Mean, Time Between, Failure. (MTBF) follows normal distribution. The MTBF distribution of a machine that has passed the phase of early failures exhibits a normal distribution. The smaller the standard deviation of this distribution the more likely this machine will be a candidate for preventative maintenance. MTBF Is an acronym for Mean, Time Between, Failure.
