Does the type of instruction in a college sociology class (either lecture or self- paced) and its grading policy (either letter or pass/ fail) influence the performance of students, as measured by the number of quizzes successfully completed during the semester? Six students are randomly assigned to each of the four possible cells, yielding the following results:

(a) Summarize the results with an ANOVA table.
(b) If appropriate, conduct additional F tests, estimate effect sizes, and use Tukey€™s HSD test.
