(a) Let the random variable X have a continuous distribution with the probability density function (pdf) сехp(-ал) (г > 0) fx(x) = elsewhere, with a, c > 0. (i) State the conditions that need to be satisfied by the pdf and show that c = a. (ii) Compute a formula for the Moment Generating Function of X, Mx(t), and state its domain of validity. (iii) Using the method of differentiation for the Moment Generating Function Mx(t), find the mean and the variance of X. (iv) Let a new random variable, Y, be such that X := y' where p > 0. Find the pdf of Y and clearly state its domain.
