# Question

Suppose that you have 15 observations on the number of hours to failure of a unit. The observations are 442, 381, 960, 571, 1861, 162, 334, 825, 2562, 324, 312, 368, 367, 968, and 15. Is the exponential distribution a reasonable choice for the time to failure distribution? Estimate MTTF.

Suppose that you have 15 observations on the number of hours to failure of a unit. The observations are 259, 53, 536, 1320, 341, 667, 538, 1713, 428, 152, 29, 445, 677, 637, 696, 540, 1392, 192, 1871, and 2469. Is the ...Reconsider the component described in Exercise 9.1. What is the reliability of the component at 25,000 hours? 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. Continuation of Exercise 9.32. For the data in Exercise 9.32, find a 95% confidence interval on the MTTF and the reliability at 200 hours, assuming that the lifetime has an exponential distribution. In exercise 9.32 The life in hours of subsystem in an appliance has a Weibull distribution with cycles and . What is the reliability of the appliance subsystem at 10,000 hours?Post your question
