A certain electronic product is 5% likely to be "dead" out of the box. The life expectancy of the remaining inventory follows an exponential distribution with a mean of 8 years. Define random variable X to model the life expectancy (in years) of the entire (combined) inventory. (a) Mathematically describe the pdf fx(x) (b) Determine EX. I want a number, not a formula. (c) Determine and accurately plot the edf Fx(x) (d) Suppose the manufacturer provides a full replacement warranty on any product that fails within the first k years. Compute constant k such that the probability of an item being returned is 18%.
