In Gwinnett County the residents are required to have a waste service, and the fee is included in their property taxes. They do not have a choice about which company they can use. Hilary does not think this is fair and wants to appeal to the county government. She designs a survey to give to 500 randomly selected residents and attaches a sheet showing how this mandatory fee is unfair. Is this a valid survey? Why or why not?

Just tell me how to set up the equation.
