# Question

With reference to Exercise 6.17, using the fact that the moments of Y about the origin are the corresponding moments of X about the mean, find a3 and a4 for the exponential distribution with the parameter θ.

In exercise

If X is a random variable having an exponential distribution with the parameter θ, use Theorems 4.10 on page 128 and 6.4 to find the moment- generating function of the random variable Y = X – θ.
