After collecting her data and analyzing the results, she reports that the F-ratio is 13.56. a) What are the null and alternative hypotheses? b) How many degrees of freedom does the treatment sum of squares have? How about the error sum of squares? c) Assuming that the conditions required for ANOVA are satisfied, what is the P-value?
