B. The​ chi-square distribution is not symmetric.
C. The values of​ chi-square can be zero or​ positive, but they cannot be negative.
D. The​ chi-square distribution is different for each number of degrees of​ freedom, df equals n minus 1.

Answer:

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.
