Check that the requirements for the theoretical model are met for the data on semester average marks and hours spent working. When the professor checked the data, she noticed that there were two unusually low marks: a 22 and a 28. When she investigated further, she realized that the students with these low marks had withdrawn from the course (all of the other students completed the course). As a result, these two data points should not be included in the data set. Reassess the data, with these two erroneous data points removed.
