A professor decides to develop a program to wean students in two of her courses off coffee. She recruits 10 coffee-addicted students (5 students from each of the two courses: PSYC 2021 and PSYC 2022) and alternates 3 weeks of counterbalanced treatments; complete withdrawal, gradual decrease and substitution of another substance (herbal tea) with weeks of unrestricted coffee drinking. She counts the number of cups of coffee imbibed during the unrestricted day following completion of each treatment. Run an analysis of variance using the SS provided in the below table and fill out the remaining sections of the ANOVA table. Perform any appropriate post-hoc tests using Scheff test.
