Expected Value of a Continuous Random Variable

Random Variable Mean and Variance

SOLVED:The probability distribution of a random variable X is given. Compute the mean, variance, and standard deviation of X. x -198 -195 -193 -188 -185 P(X=x) .15 .30 .10 .25 .20

SOLVED:The variance of a continuous random variable, denoted V(X) or σ^2, is defined to be V(X)=E[(X-μ)^2], where μis the expected value, or mean, of the random variable X. Find the variance of the random variable in Problem 37.
