Suppose that a safety group surveyed 1,200 drivers. Among those surveyed,78% said that careless or aggressive driving was the biggest threat on the road, and 33% said that cell phone usage by other drivers was the driving behavior that annoyed them the most. Based on these data and assuming that the sample was a simple random sample, construct and interpret a 99% confidence interval estimate for the true proportion in the population of all drivers who are annoyed by cell phone users. The confidence interval estimate is _____ to _____. (Round to three decimal places as needed. Use ascending order.)
