I'm working on the following problem:
Using Central Limit Theorem, compute the number of people to poll in a public opinion survey to estimate the fraction of the population that will vote in favor of a proposition within $\alpha$ percent, with probability at least $1 - \beta$.
I'm a bit confused on how the Central Limit Theorem can be applied to this problem. The Central Limit Theorem has to do with a distribution of i.i.d. random variables converging to a normal distribution. I don't see how to pose this problem in a way that will allow me to make use of the theorem. Can anyone help me out here?
