Suppose that a safety group surveyed 1,100 drivers. Among those​ surveyed, 65​% said that careless or aggressive driving was the biggest threat on the​ road, and 25​% 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 95​% 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 ??––––––??> ​(Round to three decimal places as needed. Use ascending​ order.) Interpret the confidence interval estimate.     A. There is a 0.95 probability that the population proportion of drivers who are annoyed by cell phone users is in the interval.   B. There is 95​% confidence that the population proportion of drivers who are annoyed by cell phone users is in the interval.   C. There is 95​% confidence that the population proportion…
