What is the failure rate for the time to failure distribution given in Exercise 14.10, if it can be obtained? If it cannot be obtained, explain why that is the case.
Â
Exercise 14.10
The design of an electrical system is being contemplated, with an eye toward using enough components in a parallel system to provide acceptable reliability. Assume that the time to failure for each component is approximately normally distributed with a mean of 4500 hours and a standard deviation of 400 hours, and that the components are independent. If the probability of failure within the first 5,000 hours is to be less than .005, how many components should be used?
