Answer to Question 1

ANS: C
A sample is that group of people who are representing the entire population and participating in the study. Samples are expected to represent an entire population.
The accessible population is that portion of the entire population that the researcher can actually use.
An element is an individual unit of a study population.
The target population is the entire set of individuals who meet the sampling criteria.

Answer to Question 2

ANS: B
Identifying all paths expressing relationships between the concepts described in the study is critical for model testing for causal relationships. Causal relationship testing necessitates that the connections between the concepts be described and investigated.
The model testing design requires that all variables relevant to the model be measured.
Model testing requires a large, heterogeneous sample to provide a large enough and representative sample required for the study.
Random sampling techniques, rather than convenience sampling techniques, are necessary for this type of study.

Many people have small pouches in their colons that bulge outward through weak spots. Each pouch is called a diverticulum.
