    A) The mean of the chi-square distribution is 0

    A) is not a property of chi square distribution.

    Step-by-step explanation:

    We have to find the properties of a chi square test.

    A) False

    The mean of a chi square distribution is equal to the degree of freedom.

    B) True

    The chi-square distribution is non symmetric.

    C) True

    The chi square value can be zero and positive.

    It can never be negative because it is based on a sum of squared differences.

    D) True

    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.
