Question
A certain type of device has an advertised failure rate of 0.0125 per hour. The failure rate is constant and the exponential distribution applies. (a)
A certain type of device has an advertised failure rate of
0.0125 per hour. The failure rate is constant and the exponential distribution applies.
(a) What is the mean time to failure?
(b) What is the probability that 320 hours will pass before a failure is observed?
(c) Suppose that there have been no failures in the last 160 hours. What is the probability that there will be no failures after an additional 320 hours have passed?
