Suppose a random variable X follows the Rayleigh distribution with probability density function given by f(x) = x/sigma^2 e^, 0 lessthanorequalto x < infinity, 0 < sigma < infinity. The cumulative distribution function is F(x) = 1 - e^, 0 lessthanorequalto x < infinity. The mean and variance of a Rayleigh random variable are. respectively. E(X) = sigma squareroot pi/2 and var(X) = (4 - pi/2) sigma^2. Plot the Rayleigh probability density function...
