For the reliability function r(t) - e-(m1000), use eqs. (3.13) and (3.14) and compare the upper and lower bounds with the actual reliabilities at 100, 200, 500, 800, 1000, 2000, 5000, and 10,000 hr. this failure distribution has an ifr with an mttf of 1772.46. 3.22 show for the exponential distribution that the residual mean life is 1/2. regardless of the
