Question

PROBLEM 4 Agricultural experts are trying to develop a bird deterrent to reduce costly damage to crops. An experiment is to be conducted using garlic oil to study its effectiveness as a nontoxic, environmentally safe bird repellent. The experiment will use three species of birds that causes the most damage annually to the corn crop. Food granules made from corn are to be infused with garlic oil in each of three concentrations of garlic: 0 percent, 25 percent, and 50 percent. The researchers will determine the adverse reaction of the birds to the repellent by measuring the number of food granules consumed during a two-hour period following overnight food deprivation. There are 75 birds of each species available for the experiment, and the researchers will use 25 birds for each concentration of garlic. In this experiment, what are the experimental units, the treatment levels and the treatments, the independent variables, and the response variable?

Explanation / Answer

1) The experimental units

The birds

2) the treatments are garlic concentrations

3 ) the treatment levels are 0 percent , 25 percent and 50 percent of oil in the food grains

4) garlic oil consumed are independent variables

5) number of food grains consumed response variables.
