Censored Data An experiment is conducted to test the lives of car batteries. The experiment is run for a fixed time of five years. (The test is said to be censored at five years.) The sample results (in years) are 2.5, 3.4, 1.2, 51, 51 (where 51 indicates that the battery was still working at the end of the experiment). What can you conclude about the mean battery life?
