Question 3: Seven identical components were put on a test at the same operational conditions. Two components were stopped functioning before they failed, while the test were continued for the rest of the components until they failed. Following table presents the test results. Status Failure Suspension Failure Failure. Failure ● Suspension Failure 2 Time to Status, hours 3 8 13 22 35 55 70 a) Considering a one-parameter exponential distribution, using rank adjustment concept and applying Bernard's approximation method: Estimate the component reliability function by probability plotting method. . Estimate the component reliability after 20 hours. b) Considering a two-parameter Weibull distribution, using rank adjustment concept and applying Bernard's approximation method and probability plotting method: ● Estimate the component reliability after 20 hours by probability plotting method. Estimate the time, at which the component reliability would be 95%. Question 3: Seven identical components were put on a test at the same operational conditions.
