Distribution of ratio std Normal and sqrt chi squared

[QUOTE="WWGD, post: 6018895, member: 69719"] Thanks, so a chi can coincide with a normal? I know there are issues with the square root not being an injection ( or not bijection once we choose one of the roots). I guess this is why the square root of a squared normal is not a normal? Or do we just consider the composition to be an absolute value? [/QUOTE]
