The Chi-square test for independence, the null hypothesis, and the research hypothesis: 1) always contradict each other. 2) always agree with each other. 3) are never actually stated. 4) are usually both rejected. Question 20 (4 points): A researcher reports that her obtained chi-square of -17.56 is significant because it exceeds the critical chi-square of 3.841 for an alpha of 0.05 with degrees of freedom. What mistake has been made? 1) Neither critical nor obtained chi-squares can have negative values. 2) It is impossible to have only = degrees of freedom. 3) It is impossible for the obtained chi-square to exceed 10. 4) A one-tailed test should have been used. Question 21 (4 points): The null hypothesis states that the variables are independent in the chi-square test of hypothesis.
