Answer to relevant QuestionsLet the random variable X be equally likely to assume any of the values 1/8, 1/4, or 3/8. Determine the mean and variance of X.Show that for a discrete uniform random variable X, if each of the values in the range of X is multiplied by the constant c, the effect is to multiply the mean of X by c and the variance of X by c2. That is, show that (cX) = ...Determine the cumulative distribution function of a binomial random variable with n = 3 and p = ½.This exercise illustrates that poor quality can affect schedules and costs.
