1. (5 points) A trial for the lifetime of a new battery was carried out by placing 1000 batteries inside 1000 electric toys. The toys were turned on and left to run for 72 hours. An investigator returned every 2 hours to count how many toys had stopped operating. On close analysis it was discovered that some of the toys had stopped operating. On dose analysis it was discovered that some of the toys were not switched on in the first place. Some of the toys were still running after 72 hours. For each of the following types of censoring, state with a reason whether it is present in this study: - right censoring - interval censoring - type II censoring - non-informative censoring 1.
