A survey was conducted to investigate the relationship between gender (male and females) and sector of employment (private, government and academia). Using the information provided, does a relationship exist between gender and employment sector at the 5% significance level? If the Chi-square test statistics = 0.529, what conclusion can be made?   A. Since Chi-square test statistics > Chi-square critical value, do not reject H0 B. Since Chi-square test statistics < Chi-square critical value, do not reject H0 C. Since Chi-square test statistics < Chi-square critical value, Reject H0 D. Since Chi-square test statistics > Chi-square critical value, Reject H
