Homework-7 1. Find f(t), F(t), R(t), and MTTF, assuming -- 1-1/4 25 If 200 units are placed in operation at the same time, how many failures are expected during 1 year of operation? 2. Show that expected time to failure (ETTF) is connected to the reliability function R(t). Then using R(t), derive the ETTF of the Weibull model. 3. From the definition of h(t), show that h(t)=f(t)/R(t).
