Suppose that insurance companies did a survey. They randomly surveyed 400 drivers and found that 320 claimed they always buckle up. We are interested in the population proportion of drivers who claim they always buckle up.
Compute the margin of error for a 95% confidence interval and construct this confidence interval for the population proportion who claim they always buckle up.
(i) State the margin of error. (Round your answers to four decimal places.)
(ii) State the confidence interval. (Round your answers to four decimal places.)
