QUESTION:
Problem 11E
The pdf of Y is g(y) = d/y3, 1 < y < ∞.
(a) Calculate the value of d so that g(y) is a pdf.
(b) Find E(Y).
(c) Show that Var(Y) is not finite.
ANSWER:
Step 1 of 4:
Given that the probability density function(pdf) of Y is,
g(y)=;1<y<
Firstly we have to find the value of E(Y) and then we have to show that Var(Y) is infinite.
