Suppose that you want to determine whether there is a difference between the distances traveled by an air-filled football and by a helium-filled football, and that you have managed to recruit 12 punters of varying abilities to participate in the study. Describe, in detail, the design of an experiment that does not utilize pairing. Next, describe, in detail, the design of an experiment that does utilize pairing. Which study design (a) or (b) do you think is a better study design for the purpose of this study or does it not matter

Answers

Answer 1

Answer:

a) step 1 : Divide the punters into two equal groups

  step 2 : Punters in each of the group is made to kick the ball ( i.e. Group 1    kicks an air filled football while group 2 kicks helium filled football )

step 3 : measure the average distances that the ball travelled in each group

step 4 : compare the results and draw a conclusion

b)  

Each punter is given both air filled and helium filled footballs

Each punter kicks both the air filled and helium filled footballs

The distances travelled by the balls are recorded ( measured in pairs )

c)  Design B

Explanation:

Given data:

Aim : To determine if there is a difference between distances travelled by an air-filled football and a helium-filled football

An air filled football and a helium-filled football

Number of punters recruited for the test = 12

a) Description of an experiment that does not require pairing

step 1 : Divide the punters into two equal groups

step 2 : Punters in each of the group is made to kick the ball ( i.e. Group 1 kicks an air filled football while group 2 kicks helium filled football )

step 3 : measure the average distances that the ball travelled in each group

step 4 : compare the results and draw a conclusion

b) Description of an experiment that requires pairing

Each punter is given both air filled and helium filled footballs

Each punter kicks both the air filled and helium filled footballs

The distances travelled by the balls are recorded ( measured in pairs )

c) Design B is better because the ability of each punter while kicking the balls are not the same hence there is need to allow each punter kick both balls, also for paired design/experiment.  T-test can be applied

Answer:

Based on the above map, multiethnic citizens dominate the west region of the United States.

Answer: Responses may vary. A sample response follows: When a country is diverse, it has a great deal of variety. The map shows that several racial groups make up a majority in different parts of the United States, rather than one or two groups that dominate the US as a whole. African Americans make up a majority of the population in many Southeastern counties, while Hispanic Americans dominate the population in many counties in the Southwest. White Americans are a large part of the population in the Midwest and Northeast, and Native Americans make up a majority of the population in many counties across America. Many Americans identify themselves as multiracial or multiethnic, and they are a large portion of the population in many counties as well. Because of the variety shown in the map, one can conclude that America is very diverse.

Logical reasoning cannot be learned or improved. Individuals are either naturally good at it or they are not.

Answers

The claim that logical reasoning cannot be taught or improved upon is untrue. Either people are good at it naturally, or they are not. Hence, the statement is false.

What is logical reasoning?

Induction and abduction are two categories of logical reasoning that are frequently distinguished in addition to formal deduction. Using a predetermined set of facts or data to infer other facts through logical deduction is known as deductive reasoning. It entails deriving particular conclusions from premises.

These three categories of thinking can be explained as follows within the framework of a mathematical model. The building/creation of the model's structure is abduction. Induction is the process of giving values (or probability distributions) to the model's parameters. Deduction occurs during model execution.

Consider the following scenario. Use your knowledge about scientific evidence to answer the question that follows.
Concrete, used in sidewalks, is composed of three substances: cement, an aggregate (like sand), and water. When mixed together, these three substances produce a reaction in which calcium ions are formed. The product of this chemical reaction is what is known as concrete. Each time you perform this experiment, you get the same result. Which of the following statements describe the results produced by this experiment?
a. The results provide evidence that rests on an argument from authority.
b. The results provide anecdotal evidence.
c. The results provide empirical evidence derived from observations of the natural world.
d. The results provide evidence that is replicable, or repeatable, in future experiments.

Answers

Answer:

D

Explanation:

If these three substances are mixed together with the required proportion, it would yield concrete all the time. Thus, the result is replicable, or repeatable, in future experiments.

The result is not from an observation of the natural world because the three substances were mixed together by man in a lab.

5. Two objects of the same mass are in a room. At which of the following distances will the greatest gravitational force be exerted by one object on another?

6. What type of forces causes changes in motion?

7. What type of force is gravitational force?

Answers

Answer:

Explanation:

During weathering, rocks and minerals are broken down and worn away by the action of natural forces such as wind, water, ice, and temperature changes.

Over time, the underground of the limestone plateau is likely to change due to the process of dissolution. This occurs when water moves through cracks and crevices in the surface and dissolves the limestone, creating underground caves and channels.

The method of heat transfer that can take place without matter is radiation. This occurs when heat is transferred through electromagnetic waves, such as infrared radiation.

The type of heat transfer that takes place when a furnace heats up an entire room is convection. This occurs when heat is transferred through the movement of fluids or gases, such as air.

The greatest gravitational force will be exerted by one object on another when they are at the shortest distance.

Forces that cause changes in motion are called external forces.

Gravitational force is a type of force that arises from the interaction between masses. It is the force that attracts objects with mass towards each other.
