Question
An experiment is conducted to study the longevity of engine timing belts made of a new type of material.
The experiment is run for a fixed time of 8 years. (Thus, the test is censored at 8 years). The sample
results (in years) are
6 5.8
2.6
8+ 8+
(where 8+ indicates that the timing belt was still in tact at the end of the experiment). What can you say
about the "average“ life span of one of these timing belts?
The median timing belt life (in years) is
The mean timing belt life (in years) is greater than
