She tried each jump 6 times in random order, using two of her skating partners to judge the jumps on a scale from 0 to 6. After collecting the data and ana-lyzing the results, she reports that the F-ratio is 7.43. a) What are the null and alternative hypotheses?b) How many degrees of freedom does the treatmentsum of squares have? How about the error sum ofsquares?c) Assuming that the conditions are satisfied, what is theP-value? What would you conclude?d) What else about the data would you like to see in orderto check the assumptions and conditions?
