Listen to our expert Sébastien Blachère while he shares the basic statistics needed to understand the meaning of this L10 life. Explanation is given on the correct interpretation of the L10 life, as well as higher reliability levels like the L5 or L1.
WebA Weibull distribution is a generalized gamma distribution with both shape parameters equal to k. The translated Weibull distribution (or 3-parameter Weibull) contains an … Web(iii) From past experience it is known that the lives of ball bearings, measured in millions of revolutions, follow a Weibull distribution with a = 75 and b = 3. However, after a change in production process, it is thought that b should remain unaltered but that the value of a might have changed. A random sample of 12 ball bearings was tested ...
