Answer:
The sample size
Explanation:
Dr. Prometheus aims to analyze the viewpoints of all 18-year-old Houstonians regarding marijuana legalization. She has randomly selected 500 individuals from that demographic to participate in her survey. In this case, the population being evaluated is the sample size. The sample size of a study refers to the number (n) of observations gathered from a population, which serves as the basis for making statistical inferences regarding the entire population or the number of participants whose data forms the foundation of the research conclusion.
Response:
C) the third-variable criterion
Rationale:
In this context, the variables of interest are children's exposure to television and their corresponding levels of aggression. The independent variable is the children's exposure to television, while the dependent variable is the child's aggression.
Nevertheless, you are questioning whether another factor, peer pressure, influences these two variables. When a separate variable affects two other variables, it is referred to as the third-variable criterion. Thus, I focus on the third-variable criterion.
The accurate response is to allow the slave trade to continue for 20 additional years.
