Chapter 4, Problem 12PT

a.

To determine

To find: The experimental units, response variable and the treatments.

Explanation of Solution

Given:

Elephants some of the time harm trees in Africa. It turns out that elephants loathe honey bees. They perceive hives in where they are normal and evade them. A bunch in Kenya put dynamic bee sanctuaries in certain trees and void bee sanctuaries in others. Whether elephant harm be less in trees with hives. Specialists to plan an examination to reply these inquiries utilizing 72 acacia trees

The experimental units are considered as the part of original population for which the researcher collects the information. Here, experimental units are 72 chosen acacia trees.

Treatments are imposed on subjects to get their opinions by an experiment. Here, empty, no beehive and place active are treatment.

A response variable is a variable that is used to measure the outcome. Here, the total damage that has been caused by the elephants.

b.

To determine

To discuss: The process that that could be used by the researchers to proceed a completely randomized design for the provided experiment.

Explanation of Solution

The number of treatments and acacia trees are 3 and 72 respectively. Hence, each treatment should be received by 24 trees.

Following procedure must be used:

1. A number between 01 and 72 should be assigned to each tree.
2. A row must be chosen.
3. Chose the first two-digits of numbers.
4. Repeat the process till the 24 trees get treatment 1.
5. Follow the procedure for treatments 2 and 3.
