15) As part of a study at a large university, data were collected on 224 freshmen computer science 1 (CS) majors in a particular year. The researchers were interested in modeling y, a student's grade point average (GPA) after three semesters, as a function of the following independent variables (recorded at the time the students enrolled in the university): xi-average high school grade in mathematics (HSM) x2 = average high school grade in science (HSS) x3-...
