Final answer:
Incorporating more variables for analysis supports both decision making and problem solving. Case study results aren't generally applicable, and a price ceiling doesn't shift demand or supply. Symbolic interactionists typically use participant observation for research. Option C is correct.
Step-by-step explanation:
As companies transition from data to knowledge, they will begin to incorporate a larger number of variables for analysis to provide better, more accurate support. The correct answer to the student's question is C. Both A & B, meaning that more variables in analysis lead to improved support for decision making and problem solving.
Regarding case studies, they are known to provide in-depth results but those results are not generally applicable to larger populations, which means the best answer is b. Its results are not generally applicable. When discussing a price ceiling, it is a regulatory measure that does not shift demand or supply. Therefore, a price ceiling will usually shift d. neither.
Lastly, a symbolic interactionist is most likely to utilize b. Participant observation as a research technique because it aligns well with studying the complex relationships and meanings within a society.
