Suppose A recent survey conducted by a local university revealed that 80% of students are in favor of implementing a composting program on campus. The survey also found that students believe that a composting program would help reduce waste and promote sustainability. Several students have already volunteered to help launch the program and educate their peers about the benefits of composting.
Can we infer that "All students are opposed to the idea of a composting program."? Yes, no, or maybe?
