A life testing plan is to be terminated after the eighth failure. It should reject a lot that has an acceptable mean life of 900 hours with a probability of 0.10. Items that fail during the test are not replaced. A sample of 15 items is placed on test with the eight failures occurring at the following times (in hours): 400,430,435,460,460, 490, 520, 530.
