A team of educational researchers want to assess traditional classroom instruction compared to online options. Students who are enrolled in a course will be randomly assigned to one of three sections: Students in Section 1 will take the class in a traditional classroom. Students in Section 2 will take the course online with an interactive video cast of the instructor wherein students can ask the instructor questions during the session. Students in Section 3 will take the course online and view a prerecorded video of the professor delivering the lecture. The researchers will gather the course grade of each student (0% . . . 100%). Additionally, students will be asked to complete a course satisfaction survey (1 = Extremely unsatisfied . . . 10 = Extremely satisfied).

a. Write the hypotheses.
b. Run each criterion of the pretest checklist (n quota, normality, moderate correlation, homogeneity of variance-covariance [Box’s M test], and homogeneity of variance [Levene’s test]) and discuss your findings.
