A) are variables that scientists keep controlled in experiments to rule out measurement error. B) are working premises set up to be falsifiable. C) have values that may change by an infinitesimally small amount, rather than in units of some predetermined size. D) have values that remain the same in repeated experiments that help scientists make stronger conclusions. E) fall outside of a typical bell curve.

Exam 1: The Scientific Method

You have been hired as a consultant to work with a group of people in a small town. The town is facing problems with a decision on whether to develop agricultural land for housing and commercial uses or keep it as agricultural land. The town is split three ways: (1) all housing and commercial uses; (2) all agriculture; and (3) find a way to do both. Explain how you can use game theory to help you in your work. Be sure to include problems with game theory you may encounter.

Question 1

Correct Answer:

Verified

Using game theory, have each group decide how their solution would be beneficial to the entire town if they cooperate. Problems that may arise are if one group does not cooperate and the town cannot reach a consensus. Before starting the resolution, rules need to be set for when a consensus is met; for example, when X amount of the people agree on a solution.

Question 2

Correct Answer:

Verified

The model should include birth control options, population size, amount of food, water, medical care, lifespan, death and birth rates, current water consumption, water availability, etc. Variables should be changed one at a time to see how they relate to the other components.

Question 3

Correct Answer:

Verified

An experiment to test this will need to control wind, you would measure the height, you would have to make sure they were both dropped at exactly the same time, you would want to time the fall with a stopwatch or other timing device. You would want to repeat the experiment many times.

Question 12

You are working for a company that produces fertilizers. They want you to create a new "green" fertilizer. You ask the question, "Will the 'green' fertilizer produce a large enough yield of corn to be marketable?" You hypothesize that the "green" fertilizer will not be as effective as a synthetic fertilizer. You design an experiment to control the brand and amount of seeds planted, the sunlight, soil type, temperature, and amount of water applied. You set up two fields: one that will use the "green" fertilizer and one that will use the synthetic fertilizer. At the end of the study the data show that the field with the "green" fertilizer produced a greater yield of corn. Which of the following would you chose for the conclusion of your study?
