A) 5.99
B) 7.81
C) 9.49
D) 11.07
Critical Value
A threshold in hypothesis testing that defines the boundary between the region where the null hypothesis is rejected and where it is not.

Final Answer :
B
Explanation :
The degrees of freedom for this chi-square test would be (2-1)(4-1) = 3. Looking at a chi-square distribution table with 3 degrees of freedom and α = .05, the critical value is 7.81.
