The question is incomplete and the full version can be found online.  

Answer: The change in IQ score from the first to second test

Explanation:

In an experiment, the response variable is the purpose of the question that is being made, while the explanatory variable is the one that has an effect over the response variable, meaning that it explains any changes in it.

If Brian is examining the effect that exercise might have on a person's intelligence quotient (IQ), the question he´s making is: does exercising change IQ results? Therefore, the change in IQ is the response variable. The amount of exercise is the explanatory variable, and the experiment aims to determine whether or not it has an effect on the response variable.

Incorrect options: The number of people in the study is the sample under study, not the response variable. The first IQ test score would be one indicator of the variable, not the variable itself. And the amount of exercise the people do is the explanatory variable, not the response variable.

"all college students who drink beer make less than a 4.0 g.p.a. it is obvious then that drinking beer lowers a student's grades
Ket [755]
This is an example of someone who believes that correlation proves causation.
Correlation between the GPA of students who drink beer and the GPA of those who don't according to this person will cause the belief that beer is the reason why their GPA is lower than those students who don't drink beer, which doesn't make much sense.

What innovation do you think has had the most influence on expanding the American<br> economy? Why?
4vir4ik [10]

Answer:

It is reasonable to argue that the <em>invention of the internet</em> had the most influence on expanding American economy.

Explanation:

<u>The internet </u>had a <u>significant effect on cost savings in many sectors of economy, that lowered the prices of products and services</u> and thus increasing living standards and economic growth. It also<u> increased management efficiency to manage companies supply chains more effectively, making transactions cheaper and quicker.</u>

For example, online retail had a revolutionary impact on American economy. Thanks to online retail companies, such as Amazon, shopping has become much faster and easier on the customers side. Customers no longer have to spend time going to the shop, they can make quick purchases online and get their order delivered to the doorstep. On the other hand, online retail companies do not need to rent shopping spaces anymore, they rather need to build super efficient fulfillment centers.
