Suppose a candidate for public office is favored by only
Suppose a candidate for public office is favored by only 48% of the voters. If a sample survey randomly selects 2500 voters, the percentage in the sample who favors the candidate can be thought of as a measurement from a normal curve with a mean of 48% and a standard deviation of 1%. Based on this information, how often would such a survey show that 50% or more of the sample favored the candidate?
