Problem 8-32 You are conducting a reliability analysis for a new product. Based on prior testing with a similar product, you bel
ieve the Weibull failure-time distribution, with parameter lambda=.200 per year, applies. But you have no basis for establishing beta. Compute at a time span of 5 years (1) the failure rate and (2) the survival probability assuming that
(a) beta=0.1
failure rate=
survival probability=
(b) beta=1
failure rate=
survival probability=
(c) beta=1.9
failure rate=
survival probability=
(d) beta=2.2

Answer: He is not correct.
Steps:
Let x1 and x2 be the first and second number, respectively.
In words, if the second is 125%, or 5/4 of the first number (first equation),
then the first is 4/5 of the second, which is 0.8 or 80%.
