The chi-square test for independence is used to determine if two categorical variables are independent or not. In this case, gender and major are both categorical variables, so this test would be appropriate to use. The goodness-of-fit test for a multinomial experiment is used to determine if observed frequencies of each category match expected frequencies, but this test is not appropriate for this scenario as we are not comparing frequencies of multiple categories. The goodness-of-fit test for normality and Jarque-Bera test for normality are both used to test if a set of data follows a normal distribution, and are not relevant to this scenario.
