At BYU-Idaho there has been a lot of interest in the performance of students in online classes. Generally, administrators are in
terested to know if there is a difference in the learning of students who take an online course compared to those who take a traditional course. A study was done to see if the grade received in the course is related to the type of course. Researchers collected the grades of students in a traditional Business Statistics class and compared those with the grades earned by students in an online Business Statistics class. Using the data below, determine if a student's grade is affected by the type of course he or she is enrolled in. Use a level of significance of LaTeX: α = 0.05. Are the requirements satisfied to conduct a hypothesis test? If they are not, complete the remainder of the problems anyway.
