Suppose you want to investigate the conjecture that statistics students at your school are more actively engaged in class than calculus
students. You regularly attend classes and rate the level of engagement based on the number of questions asked by students and the
number of students who offer responses to instructor questions. You do this for Professor Newton's 8 am calculus class, and Professor
Fisher's 11 am statistics class.
Identify two confounding variables in this study.
