The correct answer is D. Everyone has the same chance of being part of the study

Explanation:

In research, especially in types of research that deal with human subjects, it is common the researcher does not study a complete population but selects a sample or portion of it that is used to draw conclusions about all the population. Additionally, a sample can be selected in many ways following specific criteria but in general terms random sample is recommended for many cases which implies the researcher select people to study randomly or by following methods without a pattern or criteria. In this way, the participants selected are more likely to represent all the population as researches do not select participants with only certain features but everyone has the same chance of being selected and this usually guarantees there is variety in the study. Therefore, the reason random sample is an effective way to select participants is that everyone has the same chance of being part of the study.

A state statute provides: "Any merchant desiring to sell within this state any product or goods manufactured outside of the Unit
Naddika [18.5K]

Answer:The Statute is an unconstitutional violation of the Commerce Clause.

Explanation:The Statute is an unconstitutional violation of the Commerce Clause. Regulation of foreign commerce is exclusively a federal power because of the need for the federal government to speak with one voice when regulating commercial relations with foreign governments. The existence of legitimate state interests underlying state legislation will not justify state regulation of foreign commerce. The state statute, in imposing requirements for a license costing $50 and for a clear marking of goods as being from a foreign country, clearly is an attempt by the state to restrict or even eliminate the flow of such goods in foreign commerce. Thus, the statute is unconstitutional.
