问题如下：
John, an analyst, use a chi-square distributed test
statistic to test for independence of two categorical variables.
If the critical value for the 0.05 level of significance is 9.4877, John will reject the null hypothesis when the test statistic calculated is:
选项：
A.
- 25.48
B.
32.085
C.6.5847
解释：
B is correct.
We reject the null hypothesis that these groupings are independent when the calculated statistic exceeds the critical value.
请问如果题目中，给出两个数值都大于critical value，但是其中一个数值比另一个更大，那么答案就是选最大那个数值对吗？就是测验独立性不是应该等于0是说明是独立的，怎么答案会有负数？
