1. Suppose that the probability density function (p.d.f.) of the lifetime (in days) of a particular type of component is (see attachment). (a) What is the expected lifetime of a component? (b) Compute the standard deviation of the lifetime of a component? (c) Compute the probability a component will fail in less than 365 days. (d) Determine P (Y ≤ 365) and compare it to the answer in part (c).
