SOLVED:The grade point average for college students is based on a weighted mean computation. For most colleges, the grades are given the following data values: A(4), B(3), C(2) D(1), and F(0). After 60 credit hours of course work, a student at State University earned 9 credit hours of A, 15 credit hours of B, 33 credit hours of C, and 3 credit hours of D a. Compute the student's grade point average. b. Students at State University must maintain a 2.5 grade point average for their first 60 credit
