Problem 1E

Let Y be a random variable with probability density function given by Step-by-Step Solution:

Solution :

Step 1 of 5:

Let Y be a random variable with probability density function is given by Our goal is:

a). We need to find the density function of .

b). We need to find the density function of .

c). We need to find .

d). We need to find E( ), E( ) and E( ).

e). We need to find E( ), E( ) and E( ) by the methods of chapter 4.

a).

Now we have to find the density function of .

Then we have to find .    =  =  = Then the distribution function of is .

And the density function of is  Step 2 of 5

Step 3 of 5
