Continuation Question from my previous question about the Council Survey...

The City council for a large city wanted to know what proportion of the residents thought fitness classes should be available to everyone. The research department offered to cooperate in conducting a survey, and a simple random sample of 500 voters was selected from all the registered voters in the city. A survey form was sent by mail to these 500 voters.

4 All the residents on the list of registered voters.

5.The 500 residents who got the mail survey.

Question #2
