In a time-terminated life testing plan, it is desired to reject lots with a mean life of 1500 hours with a probability of 0.95 and also to reject lots with a mean life of 7500 hours with a probability of 0.10. The test is to be terminated by 2500 hours. Items that fail during the test will be replaced. Assuming the time-to-failure to be exponential, determine the plan using Handbook H-108.
