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:

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

Step 2 of 3
