Not much is known about the shape of the distributionj it could easily be s-Normal. I 2. The time for 10% failures is not known well; it Is probably between 0 and 800 hr. 3. Only ballpark ideas about the distribution are known. 4. The estimates of the distribution are quite different than from the censored version of Data Set B.
