You'have just completed a reliability improvement test for ánewly designed component to be used within an aero enginethat is manufactured by a big multinational company. Thiscomponent went through 500 operational

hours of reliabilityimprovement testing and during this period there were 10failures, and consequently 10repairs/replacements/maintenances. These ten unscheduledrepairs/replacement/maintenances occurred at the followingtimes: 0.6, 6.7, 19.2, 40.3, 51.3, 75, 197.1, 256.1, 491 and 496.chours. Apply a Power Law NHPP Model to this test data and to 3decimal places, what is the unbiased estimate for the reliabilitygrowth slope of this model?
