The service life (in hours) of a semiconductor has an approximate exponential failure time distribution. Ten semiconductors
Question:
The service life (in hours) of a semiconductor has an approximate exponential failure time distribution. Ten semiconductors are placed on life test until four fail. The failure times for these four semiconductors are 585, 972, 1,460, and 2,266 hours.
a. Construct a 95% confidence interval for the mean time β until failure for the semiconductors.
b. What is the probability that a semiconductor will still be in operation after 4,000 hours? Find a 95% confidence interval for this probability.
c. Compute and interpret the hazard rate for the semiconductors. Construct a 95% confidence interval for this hazard rate.
