Question

A chi-square test of independence for a two-way frequency table with rows and columns results in a test statistic of 20.18.What can you conclude about the p-value for this test?
A) p < 0.025
B) 0.025 < p < 0.05
C) 0.05 < p < 0.10
D) p > 0.10

Without knowing the degrees of freedom or significance level, we cannot determine the exact p-value. However, a chi-square test statistic of 20.18 suggests that the observed data deviates significantly from the expected values under the null hypothesis. Therefore, we can conclude that the p-value is small, and we can reject the null hypothesis at a significance level of 0.10 or lower. Choice C is the only option that satisfies this condition.
