Question

For each of the following situations, give the degrees of freedom for the group (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 50 of his hens to each of the three treatments.

Explanation / Answer

Response: egg cholesterol level

Population: chickens with different diets or drugs

I = 3, N = 150, n1=n2=n3=50

DFG=3-1=2

DFE=149-2=147

DFT=150-1=149

F(2,147)

numerator df=2

denomenator df=147
