A researcher uses analysis of variance to test for mean differences among three treatments with a sample of 12 in each treatment.  The F-ratio for this analysis would have what df values?

Last week Sarah had exams in Math and in Spanish.  On the Math exam, the mean was µ = 40 with σ = 5 and Sarah had a score of X = 45. On the Spanish exam, the mean was µ = 60 with σ = 8 and Sarah had a score of X = 68. For which class should Sarah expect the better grade?
