Your instructor wonders which method of getting to school is faster. She records the time it takes to get to school via bus, driving the side streets, driving on the highway, and bicycling, using 10 trips for each method. After collecting her data and analyzing the results, she reports that the F-ratio is 8.76. What are the null and alternative hypotheses? How many degrees of freedom does the group sum of squares have? How about the error sum of squares? Assuming that the conditions required for ANOVA are satisfied, what is the P-value? What would you conclude? What else about the data would you like to see in order to check the assumptions and conditions?
