Calculate relevant summary statistics that will be useful in an ANOVA analysa. Create an ANOVA table for the data using the originul or AATI Ilues ahove: (It is usc RIs relevant functions: ) good idea t Evaluate the ANOVA assumptions mmerically and graphically: Was ANOVA appropriate for this data? Based on the ANOVA table mak colclusion the context of the problem Use R to obtain the relovant multiplier and then create 95% CIs for nll pairwise using tbc Tukey method , Do this bv comparisons f meAIL hud ad show Jour #ork: You W usO R to check your antuurs.
