Solution

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 25 of his hens to each of the three treatments.

The response variable is egg cholesterol level and the populations are chickens with different diets or drugs. = TRUE

A researcher is interested in students\' opinions regarding an additional annual fee to support non-income-producing varsity sports. Students were asked to rate their acceptance of this fee on a five-point scale. She received 94 responses, of which 31 were from students who attend varsity football or basketball games only, 18 were from students who also attend other varsity competitions, and 45 who did not attend any varsity games.

The response variable is the kind of varsity games the student is attending and the populations are the three groups of students. = FALSE
( Because , here response varaible is= students\' opinions regarding an additional annual fee to support non-income-producing varsity sports and population = all the students who responded )
