A researcher is interested in student characteristics based on their degree programme. As part of her study, she investigates whether psychology and maths students are equally likely to have been to a bar over the previous weekend. Her survey provides the frequency of going to a bar or not going to a bar for a sample of 90 psychology students and 90 maths students. What type of test can she carry out on the data?Question 8Answera.Chi-Square Testb.McNemar Testc.Independent Sample T-Testd.Pearson's correlation

he chi-square test is used to determine:a.The difference between two population meansb.The relationship between two categorical variablesc.The correlation between two continuous variablesd.The significance of the sample sizeClear my choice

A table represents the number of students who passed or failed an aptitude test at two different campuses.East Campus West CampusPassed 48 37Failed 52 63In order to determine if there is a significant difference between campuses and pass rate, the chi-square test for association and independence should be performed.What is the expected frequency of West Campus and failed?50 students63 students50.7 students57.5 students

Which statement is not true about both the chi-square and McNemar test?Question 12Answera.Both tests are used on frequency data (or counts)b.The data in separate cells of the contingency table must come from different participants (independent sample)c.The test statistic is based on comparing the observed frequency of an event, with the expected frequency of the event if the null hypothesis is trued.They are non-parametric tests

A particular state university system has 7 campuses. On each campus, a random sample of students will be selected, and each student will be categorized with respect to political philosophy as liberal, moderate, or conservative. The null hypothesis of interest is that the proportion of students falling in these three categories is the same at all 7 campuses.(a) On how many degrees of freedom will the resulting test 𝜒2 be based?
