A light bulb manufacturer wants to produce light bulbs that last approximately 700 hours, but some bulbs burn out earlier than others. We define F (t) as the fraction of the bulbs that are they melt before t hours, so that F (t) is always between 0 and 1. a) Sketch what might be the graph of F. b) What is the meaning of the derivative r (t) = F'(t)? c) What is the value of the integral from 0 to ∞ r (t) dt? Explain.
