If n = 420 and p = 0.6, construct a 99% confidence interval about the population proportion. Round your answers to three decimal places. Preliminary: a. Is it safe to assume that n < 0.05 of all subjects in the population? O No O Yes b. Verify np (1-p) ≥ 10. Round your answer to one decimal place. np (1 - p) = Confidence Interval: What is the 99% confidence interval to estimate the population proportion? Round your answer to three decimal places. <p<
