A university has three schools: Arts, Business, and Science. The average GPA for students in each school and the number of students are given in the table: | School | Number of Students | Average GPA | |----------|--------------------|-------------| | Arts | 300 | 3.2 | | Business | 200 | 3.5 | | Science | 500 | 3.0 | What is the overall average GPA for all students at the university?
✓ Correct Answer: Option B
Overall average GPA is a weighted average: (300*3.2 + 200*3.5 + 500*3.0) / (300 + 200 + 500). This calculates to (960 + 700 + 1500) / 1000 = 3160 / 1000 = 3.16.
