 “Do people perform better on exams when they wear their favorite color?” is a scientific question because it can be tested by a systematic procedure.

Explanation: To know whether people do good in an exam depending on what color they are wearing, an experiment can be conducted by asking the subjects to wear their favorite color to an exam. The same subjects can be then asked to wear colors other than their favorite colors and give an exam with a similar level of difficulty as before. The results of both the exams can be analyzed and can thus be concluded whether or not wearing the favorite color has anything to do with the performance in the exam or not. Hence, the question asked is a scientific question.
