Question

Elephants sometimes damage trees in Africa. It turns out that elephants dislike
bees. They recognize beehives in areas where they are common and avoid them. Can
this be used to keep elephants away from trees? A group in Kenya placed active
beehives in some trees and empty beehives in others. Will elephant damage be less in
trees with hives? Will even empty hives keep elephants away? Researchers want to
design an experiment to answer these questions using 70 acacia trees.
a. Identify the experimental units, treatments, and the response variable.

b. Describe how the researchers could carry out a completely randomized design for
this experiment. Include a description of how the treatments should be assigned.

Answer:

a)

b)

We assing each tree a unique number from 1 to 70. Putting these numbers in a lucky draw/hat, the first X numbers drawn will have active beehives, the next Y drawn will have empty beehives. the last (70-X-Y) will have no beehives.
