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 ...Continuation of Exercise 9.11. If a Weibull distribution has a shape parameter of , it can be reasonably well approximated by a normal distribution with the same mean and variance. For the situation of Exercise 9.11, ...Consider the following 20 observations on time to failure: 702, 507, 664, 491, 514, 323, 350, 681, 281, 599, 495, 254, 185, 608, 626, 622, 790, 248, 610, and 537. Is either exponential or the Weibull a reasonable choice of ...Consider the parallel system shown in the accompanying figure. The reliability for each component is shown in the figure. Assuming the components operate independently, calculate the system reliability. Suppose that 50 units are tested for 1,000 cycles of use. At the end of the 1,000-cycle test period, 5 of units have failed. When a unit failed, it was replaced with a new one and the test was continued. Estimate the ...Post your question
