For the data in Exercise 9.32, find a 95% confidence interval on the MTTF and the reliability at 200 hours, assuming that the lifetime has an exponential distribution. In exercise 9.32 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 ...
