In a survey funded by the University of Washington School of Medicine, 640 of 1,600 adult Seattle residents said they did not believe they could come down with a sexually transmitted infection (STI). Construct a 99% confidence interval estimating the proportion of adult Seattle residents that do not believe they can contract an STI. Round the answers to three decimal places. Preliminary: a. Is it safe to assume that n < 5 % of all residents in Seattle? Yes ON O b. Verify np (1- ê) > 10. Round your answer to one decimal place. пр(1 — р) %3 Confidence Interval: What is the 99% confidence interval to estimate the population proportion? Round your answer to three decimal places. < p <
