An experiment to study lifetime (in hours) for certain kind of component involved putting 10 components in operation and observing them for 100 hr. Eight of components failed throughout that period, and those lifetimes were recorded. The lifetimes of the two components still functioning after 100 hr are recorded as 100+. There were resulting sample observations. Which of the measures of center can be calculated, and what are the values of those measures? (Round all answers to two decimal places.)
