Question: A component has a Weibull time to failure distribution The value
A component has a Weibull time-to-failure distribution. The value of the scale parameter is . Suppose that the shape parameter is . Find the mean and variance of the time to failure. What is the reliability at 600 hours?
Relevant QuestionsContinuation 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.
