Question:

In Example 6.8, we introduced the concept of a censored experiment in which n components are put on test and the experiment terminates as soon as r of the components have failed. Suppose component lifetimes are independent, each having an exponential with parameter l. Let Y1 denote the time at which the first failure occurs, Y2 the time at which the second failure occurs, and so on, so that Tr 5 Y1 1... 1 Yr 1 (n 2 r)Yr is the total accumulated lifetime at termination. Then it can be shown that 2lTr has a chi-squared with 2r df. Use this fact to develop a 100(1 2 a)% CI formula for true average lifetime 1/l. Compute a 95% CI from the data in Example 6.8.
