A chi-square test for independence with 8 degrees of freedom results in a test statistic of 18.21. Using the chi-square table, the most accurate statement that can be made about the p-value for this test is that:

A) p-value < 0.01
B) 0.025 > p-value > 0.01
C) 0.05 > p-value > 0.025
D) 0.10 > p-value > 0.05

I picked C 0.05> p-value> 0.025

1. 3
1. I would pick B.

Check the table again and see what you think.
