Question

Are these assumptions necessary to use the chi-square procedure for calculating confidence intervals and hypothesis testing?

The variables are random non-negative numbers
The distribution is right-skewed
Their only parameter is the degrees of freedom
the mean (mu) and the variance (sigma^2) of the chi-squared random variable are mean (mu) = the degrees of freedom and the variance (sigma^2) =2degrees of freedom
