Suppose that the service life in hours of a semiconductor is a random variable having a Weibull distribution (see Exercise 6.23) with α = 0.025 and β = 0.500.

(a) How long can such a semiconductor be expected to last?

(b) What is the probability that such a semiconductor will still be in operating condition after 4,000 hours?
