B. 7
C. 4
D. 9
In a two-way Chi-square situation, you are trying to determine if there is a significant relationship between two variables that represent the nominal and/or ordinal scale of measurement.

B. False
What is stated by the null hypothesis in a two-way Chi-square test?

Since you have asked multiple question, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question.
It is given that:
Two-way Chi-square test is used and both variables have 4 categories or 'items'.
Let r=4
n=4
Now, the number of degrees of freedom (df) for the Chi-square test is:
=(r-1)(n-1)
=(4-1)(4-1)
=9
Option D) is correct.
