The student was likely investigating the distribution of homework nights during a week, and should use a chi-square test of independence to analyze the data.
The student was most likely investigating the nights during which the highest number of students do the majority of their homework with equal frequencies during a week. This question relates to analyzing the distribution of homework nights throughout the week. To test this hypothesis, the student should use a chi-square test of independence, which compares the observed frequencies with the expected frequencies.
The chi-square test is a statistical method used to determine if there is a significant association between categorical variables. It compares the expected and observed frequencies in a contingency table, assessing whether any deviations are due to random chance or reflect a true relationship.
