Question: Suppose that only one replicate of the 24 design in
Suppose that only one replicate of the 24 design in exercise 8.4 could be run, and that we could only conduct eight tests each day. Set up a design that would block out the day effect. Show specifically which runs would be made on each day.
Answer to relevant QuestionsShow how a experiment could be set up in two blocks of 16 runs each. Specifically, which runs would be made in each block? Suppose that a unit had a Weibull time-to-failure distribution. The value of the scale parameter is . Graph the hazard function for the following values of the shape parameter: . For the fixed values of the scale ...Reconsider the component described in Exercise 9.1. What is the reliability of the component at 25,000 hours? Consider the stand-by system in the accompanying figure. The components have an exponential lifetime distribution, and the decision switch operates perfectly. The MTTF of each component is 1,000 hours. Assuming that the ...Suppose that 50 units are placed on test, and when 3 of them have failed, the test is terminated. The failure times in hours for the 3 units that failed are 950, 1050, and 1525. Estimate the failure rate for these units.
