Question 38 (2.5 points) 4) Listen Workers take five samples of size seven from a process. For each sample, they compute the process mean. Those means are as follows: 12.05. 12.06. 12.05, 12.04, and 12.09. What is the grand mean? Do not round interim calculations. Round your final answer to three decimal points. Your Answer: Answer Question 39 (2.5 points) Listen A product has a component that is prone to failure. As a result, it has two redundant components. That is, the overall component works if any of the three redundant components works. The reliability of the three components are: 0.93, 0.84, and 0.69. What is the probability that the component will operate? Round your answer to three decimal points. Enter 0.010 as 0.010 and not as 1%. Your Answer: Answer Question 40 (5 points) Listen A product has three components. The first two are independent and have reliability of 0.80 and 0.96. The third component is prone to failure. As a result, it has two redundant components. That is, the overall component works if any of the three redundant components works. The reliability of the three components are: 0.89, 0.86, and 0.77. What is the overall product reliability? Do not round intermediate calculations. Round your answer to three decimal points, Enter 0.010 as 0.010 and not as 1%. Your Answer: 37
