2. Following are two confidence interval estimates of the mean u of the cycles to failure of an automotive door latch mechanism (the test was conducted at an elevated stress level to accelerate the failure). 3062.9 <µs3153.7, 3048.5<µ<3168.1 a. What is the value of the sample mean cycles to failure? b. One of these intervals is a 95% CI and the other is a 99% CI. Which one is the 95% CI?
