3.
a) Statement: Let U be a uniform (0,1) random variable. For any continuous
distribution function f, the random variable X defined by
X = F−1(u)
has distribution function F.
Prove the above statement. (7 marks)
b) If X is an exponential random variables with rate 1, then its distribution function
is given by
F(x) = 1 − e−x
.
Show that
x = − ln(1 − u).

Suppose that U is a random variable with a uniform distribution on (0,1). Now suppose that f is the PDF of some continuous random variable of interest, that F is the corresponding CDF, and assume that F is invertible (so that the function F-1 exists and gives a unique value). Show that the random variable X = F-1(U) has PDF f(x)—that is, that X has the desired PDF. Hint: use results on transformations of random variables. This cute result allows...
