Which of the following is not a property of the chi-square distribution?
a. the mean of the chi-square distribution is 0.
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.

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.

hey there!

12 is twice as much as 6 because 6 goes into 12 2 times.

since the rabbit is twice as tall, we should multiply the weight of the first rabbit, 0.25, by 2.

0.25 x 2 = 0.5

therefore, the 12 inch chocolate rabbit weighs 0.5 lb, or half a pound.

hope this !
