Answer:
The conclusion is false, because it is assuming that correlation = causation.
Explanation:
An important principle in statistical analysis is the principle that when correlation exist between two variables or more, it does not mean that one of the variables are causing the other to appear in a certain manner.
Remember that correlation means that you are investigating whether a relationships exists between two variables; in this example, as we can see, it is between the biodiversity in an ecosystem and the population of an insect.
The graph can be said to illustrate the result of the research; that as the biodiversity of the ecosystem goes down, the insect's population goes up. This is a form of negative correlation.
However - we do not know what is the direction of the relationship; the student concludes that as some insects die within the ecosystem, the researched insect's population goes up; assuming that the predator species died off and thus the researched insect's population increases.
Yet, it is also possible for the relationship to go towards the other direction; the researched insect population increases - perhaps by the introduction of a new food source that causes the species' population to increase - and thus, this damages the biodiversity of the ecosystem, making the population go down since it is possible that the researched insect is instead the species which is on top of the food chain at that ecosystem.
To investigate the direction of a relationship, further research need to be done and more sophisticated statistical methods need to be used.

Answer:
<h3>Establishing federalism.</h3>
Explanation:
- The founding fathers of the US Constitution strongly feared and had a distrust in a strong central government. The framers of the Constitution added the Tenth Amendment to the Bill of Rights to emphasize the limited power of the central government.
- They firmly believed in establishing federalism as they wanted the power and liberty to be directly in hands of the states and the people. Thus, the Tenth Amendment of the US Constitution states that <u>"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."</u>
In assessing the internal validity of an intervention, we try to determine if certain changes cause certain outcomes. It is relevant in studies that try to establish casual relationship. While in observational or descriptive studies, it is not that relevant. It is also possible to have internal validity in a study and not have construct validity. Example, imagine a study where you are looking at the effects of a new computerized tutoring program on math performance in first grade students.
Answer:
The United States Supreme Court.
Explanation:
The First Amendment to the Constitution of the United States guarantees citizens the right to freedom of speech. This amendment protects Legal Practitioners as it allows them to advertise in giving information to the client and potential clients. The Supreme Court in Bates v. State Bar of Arizona, however, held that Freedom of advertisement of Commercial speech by a Lawyer is guaranteed by the First Amendment and that it is unconstitutional to curtail this right.
