A) The mean of the chi-square distribution is 0
A) is not a property of chi square distribution.
We have to find the properties of a chi square test.
The mean of a chi square distribution is equal to the degree of freedom.
The chi-square distribution is non symmetric.
The chi square value can be zero and positive.
It can never be negative because it is based on a sum of squared differences.
The chi-square distribution is different for each number of degrees of freedom.
When we are working with a single population variance, the degree of freedom is n - 1.
