Question: The data in columns B and C are the failure times (in months) of a random sample of 50 tablets that Pineapple engineers have tested

The data in columns B and C are the failure times (in months) of a random sample of 50 tablets that Pineapple engineers have tested in-house. Of these 50 tablets, the majority broke (denoted by a 1) but some were still working (denoted by a 0) when the study ended. Pineapple are interested in the percentage of tablets that fail before the warranty period.

(a) The study ended at 180 months. An engineer suggests the failure time for the units that are still working should be estimated to occur at exactly 181 months, to simplify the analysis. Why would this be a bad idea?
