Part 1 A new aircraft control system is being designed that must be 97.5% reliable. This system consists of two components in series % (enter your response as a If all two of the components are to have the same level of reliability, then the level of reliability required for each component = percentage rounded to two decimal places). Part 2 A manufacturer of disk drives for notebook computers wants a MTBF of at least 50,000 hours. Recent test results for 15 units were one failure at 10,000 hours, one at 20,000 hours, and two more at 48,000 hours. The remaining units were still running at 60,000 hours. Determine the following: a) Percent of failures = (enter your response as a percentage rounded to one decimal place). b) Number of failures per unit-hour c) MTBF at this point in the testing
