Continuation of Exercise 9.11. If a Weibull distribution has a shape parameter of , it can be reasonably well approximated by a normal distribution with the same mean and variance. For the situation of Exercise 9.11, ...Consider the following 10 observations on time to failure: 50, 191, 63, 174, 71, 62, 119, 89, 123, and 175. Is either the exponential or the Weibull a reasonable choice of the time to failure distribution? A simple series system in shown in the accompanying figure. The lifetime of each component is exponentially distributed and the for each component is shown in the figure. Assuming that the components operate ...Consider the system shown in the accompanying figure. The reliability of each component is provided in the figure. Assuming that the components operate independently, calculate the system reliability. A synthetic fiber is stressed by repeatedly applying a particular load.
