For each of the following situations, identify the response variable and the populations to be compared, and give I, the ni, and N.

(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 35 of his hens to each of the three treatments.

Populations: (Select all that apply.)

all eggs laid on a farm

hens on an all-vegetarian diet

all hens on a farm

hens on a standard diet and receiving one of two cholesterol-lowering drugs

eggs with different cholesterol levels
