Answer: (c) Which of the following statements is correct based on the result of the Chi-square test? OA. At a 5% significance level, we reject the null hypothesis. There is strong evidence that perceived mental health and sex are associated. OB. At a 5% significance level, we do not reject the null hypothesis. There is little evidence that perceived mental health and sex are independent. O C. At a 5% significance level, we reject the null hypothesis.
