how do you solve this question

A farm shop had two identical bins, one containing GM sweet corn and one containing

non-GM sweet corn. Over the season, it sold 8160 ears of GM corn and 5430 ears of non-GM corn.

If we assume that each individual customer bought a dozen ears at a time, can we infer that people

prefer GM corn?

i know that 680 people bought GM corn and 452 people bought non GM corn.

but what test can we perform with just two information?
