In a recent election campaign, KLM has just consolidated that 220 registered voters out of 500 contacted, favor a particular candidate. KLM wants to develop a 95% probability or confidence interval estimate for the proportion of the population of registered voters that favor the candidate. a. Please estimate the range of interval that favor the candidate! b. Suppose that KLM would like a 0.99 probability that the sample proportion is within 0.03 of the population proportion. How large a sample size is needed to meet the required precision?
