I need help showing that if X1, X2,..., Xn are independent normal random variables, then the chi-square test statistic is a chi-square random variable with n-1 degrees of freedom.

Any help is appreciated!

I need help with the following proof

If X1;X2;...;Xn are independent normally distributed random variables, then the chi-square

test statistic is Chi-Square with n - 1 degrees of freedom.

I'm not sure how to go about this, any suggestions help!
