Question

A farmer believes that his new irrigation method would result in more crop yield than the old one. To test his theory, he applies the new method to his corn fields. A total of 6 acres of sweet corn and 8 acres of flour con are tested for the study. The farmer also thinks the method will work differently on'sweet corn and flour corn. Therefore, he divides the group into sweet corn and flour corn and then randomizes the two methods within each group: The trainer measures the yield per acre, and then measures it again one year after the method has been implemented Select one or more:


The subjects are the yield of corm

The treatments are the yield of corn

This is an example of a block design.

The treatments are the new and old irrigation methods.

The subjects are the 6 acres of sweet corn and 8 acres of flour corn

This is an example of a matched pairs experiment.

This is an example of a completely randomized experiment

Answer 1

Answer: this is an example of matched pairs experiment

Explanation:

Since the test is carried out on the 6 and 8 acres of land with each being divided into sweet corn and flour corn

Answer 2

Answer:

The correct answer are:

This is an example of a block design.

The treatments are the new and old irrigation methods.

The subjects are the 6 acres of sweet corn and 8 acres of flour corn.

This is an example of a matched pairs experiment".

Explanation:

 A farmer has been using an old irrigation method. I decided to use a new method of irrigation on his corn field which consist of a total of 6 acres of sweet corn and 8 acres of flour corn, Since his method might work differently on sweet corn and flour corn, he divided the group. Which means it's a block design.

The experiment he carried out is regarded as a matched pairs experiment because the yield is measured before and after the experiment.
