a. What is the reliability at 150 months?
b. What is the probability of failure in 300 months?
c. Now suppose shape = 1. Find the reliability at 150 months. What is the reliability at 300 months, given that the product survived up to 150 months? Compare the two resulting values and comment on your observation
