If we carry out a test to determine whether these variables are associated, is this a test of independence, homogeneity, or goodness of fit? O independence O goodness of fit O homogeneity b. Do a chi-square test with a significance level of 0.05 to determine whether gender and happiness of marriage are associated. Assume that the conditions for the chi-square test have been met. Choose the correct null hypothesis (H) and alternative hypothesis (H,). O A. Ho: Gender and happiness have equal proportions. H: Gender and happiness have non-equal proportions. O B. Ho: Gender and happiness are independent. H: Gender and happiness are associated.
