Which decision making approach should you use if you need to make a decision using last quarter's sales data?

A) Behavioral economics
B) Organizational psychology
C) Rational model
D) All of the above

D
Explanation: D) All of these are approaches to decision making that can be helpful for making decisions using objective statistics like last quarter's sales data. Using objective data does not dictate that you use any particular model to make the decisions you need; the sales data would be just one factor considered in your future decision along with factors such as your perception, biases, heuristics, and the context.
