The theoretical frequencies in the X² test are based on the null hypothesis, which assumes that there is no significant difference between the observed and expected frequencies. The X² test compares the observed frequencies with the expected frequencies based on the null hypothesis, and if the difference between them is significant, the null hypothesis is rejected. Therefore, the theoretical frequencies are based on the assumption of no difference, which is the null hypothesis.
