Dr. Lewis wants to know whether reading a textbook before or after class has an impact of how well students do in the class. He randomly samples 50 students and assigns 26 to read the textbook chapters before class and the other 24 to read the chapters after class. At the end of the semester, student grades are classified as high (A or B) or low (C, D, or F).
