14) Catherine asks a lot of questions in class. She thinks the number of questions and comments from students changes depending on the type of class. She therefore wants to know if the type of course influences the number of questions asked by students. To answer her research question, Catherine counts the number of questions asked by some of her colleagues in two courses that they have in common: the course of Dr. Roy-Charland and the course of Dr. Rousseau. The table below shows the number of questions for some students in each of these courses. For example, Ellyse asked 5 questions in Dr. Roy-Charland's class and 3 questions in Dr. Rousseau's class.
