Problem 9E

Problem 9E

Find the distribution of W = X2 when

(a) X is N(0, 4),

(b) X is N(0, σ2).

Step-by-Step Solution:

Answer :

Step 1 of 3 :

A random variable X is  normally distributed with mean  and standard deviation  .

The probability density function is

f(x) =

The claim is to find the distribution of  w =  when.

  1. X ~ N(0, 4)

  1. X ~ N(0, )

         In general,    ~ with one degrees of freedom.

Where, v =

The probability density function of v is

P( V  v) =  dy   ,       0 < v <

                 =  dy
