Of course there is a separate answer for x 2 0 and x <0 (c Let X have an exponential density with parameter λ > 0 Prove the 'Inemoryless" property: P(X > t + s|X > s) = P(X > t) for t > 0 and s > 0. For example, the probability that the conversation lasts at least t...
2. Using calculus, find the mean and variance of an exponential distribution with a probability density function of f(x)-Aet, L? (Give a proof What is A in terms of
A probability density function f(x) is an important concept in statistical sciences. It gives you the distribution of the random variable x. f(x) usually defined in a certain interval, and vanish in the rest. One can defined the median u and variances o2 as using the probability density function as (you'll see more about this later on in the course of statistic): u=L" xf(x)dx 2= (x – u)? dx For most cases the distribution function is normal or Gaussian. If...
