Answer to Question 1

2
Rationale 1: The research question is a statement of what the study concerns.
Rationale 2: A hypothesis is the expected relationship between two or more variables in a population.
Rationale 3: The researcher may have the objective or goal of studying a particular question and should remain objective during the study, but the term objective does not describe the relationship between variables.
Rationale 4: The variables in a study are generally either dependent (affected by the independent variable) or independent (affecting the independent variable). The statement being written regards the relationship between these variables.
Global Rationale:

Answer to Question 2

3
Rationale 1: A research hypothesis states the expected relationship between variables.
Rationale 2: A directional research hypothesis predicts the type of relationships that is expected.
Rationale 3: In a nondirectional hypothesis, the researcher merely predicts that a relationship exists.
Rationale 4: The null hypothesis states the absence of a relationship; it predicts that there is no relationship between variables.
