Multiple Choice

Suppose a lawyer wants to estimate the proportion of individuals in a certain neighborhood that are in favor of a new law. He knows there are 10,000 individuals in this neighborhood, and it would take far too long to survey each individual, so he would instead like to take a random sample of individuals. Assume that he would like to estimate this proportion with a margin of error of .05 or less using Slovin's formula.

n = N/ (1 + Ne²)
n = 10,000 / [1+(10,000)(0.5)²]
n = 384.615
