proof for distribution of (n-1)S^2/sigma^2 is the chi square
distribution with n-1 degrees of freedom.
I don't understand the expansion of the square, specifically how
certain terms disappeared and how a sqrt(n) appeared. Also towards
the end, why does V have a degree of freedom of 1? x A detailed
explanation of what happened from step 2 to step 3 would be very
helpful!
