Question 1
The normal distribution is an appropriate model of
◦ system reliability where components are connected in series.
◦ the full cost view of maintenance.
◦ the MTBF distribution of products, machines, or processes that have "settled in."
◦ system reliability where components are connected in parallel.
◦ the high initial failure rates of product, machine, or processes.
Question 2
Infant mortality refers to which one of the following examples?
◦ market failure of brand new products
◦ failure of products with a very short life cycle
◦ high frequency on the left side of the MTBF distribution
◦ failure of items used in the nursery ward of a hospital
◦ high failure rate often encountered in the very early stages of the lifetime of a product
