A university offers three main programs: Engineering (200 students, 85% job placement), Arts (150 students, 70% job placement), and Business (250 students, 90% job placement). The university wants to increase the overall average job placement rate. Which program, if its job placement rate increased by 5 percentage points, would have the largest impact on the *overall* average job placement rate across all programs?
✓ Correct Answer: Option C
A 5 percentage point increase in a program's placement rate will have the largest impact on the overall weighted average if that program has the largest number of students. Business has 250 students, more than Engineering (200) or Arts (150).
