An independent company randomly surveys 1,200 residents to see whether or not residents would support this proposal. The outcome of the survey shows that 60% of the residents surveyed approve of the proposal with a margin of error of 2%. Which of the following statements is a plausible conclusion from the outcome of the survey?
- Exactly 60% of city residents approve eliminating overnight parking.
- There are 72,000 city residents who approve eliminating overnight parking.
- About 2% of the city residents do not approve eliminating overnight parking.
- Between 58% and 62% of the city residents approve eliminating overnight parking.
The correct answer is: Between 58% and 62% of the city residents approve eliminating overnight parking.
Outcome of survey is 60% of residents approve the proposal with margin of error 2%.
Therefore, 
to 60% can be considered.
i.e 58% & 62% of residents approve the proposal.
