Suppose that the insurance companies did do 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 Construct a 95% confidence interval for the population proportion who claim they always buckle up What is the lower bound? (Round to 4 decimal places ) What is the upper bound? (Round to 4 decimal places)

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.) m=? (ii) State the confidence interval. (Round your answers to four decimal places.) ( ? , ? )

Question 8: A local health center noted that in a sample of 400 patients, 80 were referred to them by the local hospital. a) Provide a 95% confidence interval for all the patients who are referred to the health center by the hospital. b) What sample size would be required to estimate the proportion of all hospital referrals to the health center with a margin of error of .04 at 95% confidence?
