Answer:

c. Random

Explanation:

In this study, Dr. Guidry reaches a particular conclusion based on her research. If the numbers were collected and calculated correctly, and the study was rigorously done, then the study most likely has internal validity. However, in order for it to also have external validity, the results of the study should accurately reflect the population. Therefore, in order for this to be the case, we need to be sure that the sample drawn was indeed random.
