What are percents for percentiles?

Percents for percentiles is the percent of items expected to fail by a particular time.

Suppose you want to know when 1% of the engine windings are expected to fail. Examine the Table of Percentiles from the distribution analysis to determine the percentile associated with the percent of interest.
