At a Ikea manufacture, a kind of light bulb is produced. We take a random bulb and let .3 be its lifetime measured in years. Suppose that X N Exponential(5). what is the probabilit that this light bulb works longer than 5 years? (A) 0.368 (B) 0.500 (C) 0.632 (D) 0.993 (E) N/A Let X denote the lifetime of the light bulb in the previous problem. We denote its mea by p: and and median by 19 respectively. Which of the following comparison is true? (A) p: :19 (B) (1. >19 (C) p:
