Answer to Question 1
ANS: B
The right to self-determination is based on the ethical principle of respect for persons. This principle holds that because humans are capable of self-determination, or controlling their own destiny, they should be treated as autonomous agents who have the freedom to conduct their lives as they choose without external controls. A subject's right to self-determination can be violated through the use of (1) coercion, (2) covert data collection, and (3) deception. Coercion occurs when an overt threat of harm or excessive reward is intentionally presented by one person to another to obtain his or her compliance. In the example, offering elderly men 1,500 for one day could be considered offering an excessive reward: therefore, it is an act of coercion violating the human right to self-determination.
Answer to Question 2
ANS: A, D, E
A hypothesis is a formal statement of the expected relationship or relationships between two or more variables in a specified population. A simple hypothesis predicts the relationship (associative or causal) between two variables. A complex hypothesis predicts the relationship (associative or causal) among three or more variables. The relationships identified in hypotheses are associative or causal. An associative relationship identifies variables that occur or exist together in the real world. Causal relationships identify a cause-and-effect interaction between two or more variables. A nondirectional hypothesis states that a relationship exists but does not predict the nature of the relationship. A directional hypothesis states the nature or direction of the relationship between two or more variables.
