The following failure times are recorded and follow the Special Erlang distribution in Problem 5.19. 200, 300, 390, 485, 570, 640, 720, 720+ , 720+ , 720+ The “+” indicates censoring. What is the Erlang parameter? What is the MTTF? What is the reliability of a component from this population at time t = 500 hours? Derive the hazard-rate function expression. What is your assessment of the hazard rate?
