Test for comparing the proportion between two groups.

#1
So I am trying to figure out what test to use to find the significance between two proportions. For example, the problem reads: in 2009, 20% of participants in the contest were students and in 2019, 80% were students, if I am given the population they were taken of (200 and 500 respectively) what test do I use to establish significance between the two time points.
