We examine the effect of different inputs on determining the sample size needed to obtain a specific margin of error when finding a confidence interval for a proportion. Find the sample size needed to give, with 95% confidence, a margin of error within + 3% when estimating a proportion. Within + 2% Within + 1%. (Assume no prior knowledge about the population proportion p.) Round your answers up to the nearest integer.
