Answer to Question 1

ANS: D
Demographic variables are characteristics or attributes of subjects that are collected to describe the sample. They are often used to provide a picture of the sample and are called sample characteristics.
Extraneous variables are not necessarily demographic in nature. Demographic variables are characteristics or attributes of subjects that are collected to describe the sample. They are often used to provide a picture of the sample and are called sample characteristics.
The population parameters are connected with the entire population, not just the sample. Demographic variables are characteristics or attributes of subjects that are collected to describe the sample. They are often used to provide a picture of the sample and are called sample characteristics.
The research hypothesis indicates the expected relationship between the variables. Demographic variables are characteristics or attributes of subjects that are collected to describe the sample. They are often used to provide a picture of the sample and are called sample characteristics.

Answer to Question 2

ANS: A
Although the study will receive much criticism as to its validity, the researcher has operationalized the variable in a correct manner. An operational definition is derived from a set of procedures or progressive acts that a researcher performs to receive sensory impressions that indicate the existence or degree of existence of a variable. An operational definition is developed so that a variable can be measured or manipulated in a concrete situation. They must be independent of time or setting so that variables can be investigated at different times and in different settings.

There is no way to determine what the researcher will actually take into account for this definition.
