Question

Quizplus · Accepted Answer

The normal distribution is often used to model the MTBF distribution of products, machines, or processes that have "settled in" and are operating under normal conditions. It is not appropriate for high initial failure rates (A), system reliability in series (B), or system reliability in parallel (C). The full cost view of maintenance (E) is not related to the normal distribution.
