Survey for Biostatistics Class. Please help me out!

Hi there! My league name is Vishnu and I'm on NA. I would like to ask you guys to help me with a project for my Biostatistics class.

I would like to know what role you main and what league you are in. My null hypothesis is that regardless of rank, each role has an even number of players. My alternative hypothesis is that there is a different ratio of roles in each rank. I will run a Chi-square test to analyze the data and test my hypotheses. Here is the survey link: https://www.surveymonkey.com/s/K5RDVS8

Thank you for taking this survey and helping me out! Have a wonderful day and good luck on the Fields of Justice!
