Question: The data shown in the Table 8E 8 were collected in
The data shown in the Table 8E.8 were collected in an experiment to optimize crystal growth as a function of three variables . Large values of y (yield in grams) are desirable. Fit a second-order model and analyze the fitted surface. Under what set up conditions is maximum growth achieved?
Answer to relevant QuestionsIn exercise 8.18 Find the standard error of the effects for the experiment in Exercise 8.4. Using the standard errors as a guide, what factors appear significant? In exercise 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, ...Reconsider the component described in Exercise 9.1. What is the reliability of the component at 25,000 hours? Consider the stand-by system shown in the accompanying figure. The components have an exponential lifetime distribution, and the decision switch operates perfectly. The MTTF of each component is 500 hours. Assuming that ...
