Question: Consider the following 20 observations on time to failure 702
Consider the following 20 observations on time to failure: 702, 507, 664, 491, 514, 323, 350, 681, 281, 599, 495, 254, 185, 608, 626, 622, 790, 248, 610, and 537. Is either exponential or the Weibull a reasonable choice of the time to failure distribution?
Relevant QuestionsExplain why it is necessary to consider variability around the mean or nominal dimension as a measure of quality. Reconsider the component described in Exercise 9.1. What is the reliability of the component at 25,000 hours? A series system has four independent identical components. The reliability for each component is exponentially distributed. If the reliability of the system at 8,000 hours must be at least 0.999, what MTTF must be specified ...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. You are designing a system that must have reliability at least 0.95 at 10,000 hours of operation. If you can reasonably assume that the time to failure is exponential, what MTTF must you achieve in order to satisfy the ...
