For each of the following situations, give the degrees of freedom for the model (DFG), for error (DFE), and for the total (DFT). State the null and alternative hypotheses, H0 and Ha, and give the numerator and denominator degrees of freedom for the F statistic.
(a) A poultry farmer is interested in reducing the cholesterol level in his marketable eggs. He wants to compare two different cholesterol-lowering drugs added to the hen's standard diet as well as an all-vegetarian diet. He assigns 30 of his hens to each of the three treatments.
1. DFG =2. DFE =3. DFT =4. H0:A) The all-vegetarian diet group has a higher mean cholesterol level. B) All groups have the same mean cholesterol level. C) All groups have different mean cholesterol levels. D) At least one group has a different mean cholesterol level. E) The all-vegetarian diet group has a lower mean cholesterol level.5. Ha:A) The all-vegetarian diet group has a higher mean cholesterol level. B) At least one group has a different mean cholesterol level. C) The all-vegetarian diet group has a lower mean cholesterol level. D) All groups have the same mean cholesterol level. E) All groups have different mean cholesterol levels.6. numerator df = 7. denominator df =
