An insurance company checks police records on 566 accidents selected at random and notes that teenagers were at the wheel in 83 of them. Use this information to complete parts a through d below. a) Create a 95% confidence interval for the percentage of all auto accidents that involve teenage drivers. (11.8%, 17.6%) (Round to one decimal place as needed. Use ascending order.) b) Explain what your interval means. Choose the correct answer below. A. We are 95% confident that the true percentage of accidents involving teenagers falls inside the confidence interval limits. B. There is a 95% probability that this interval contains the true percentage of accidents involving teenagers. OC. We are 95% confident that the percent of accidents involving teenagers is 14.7%. OD. We are 95% confident that a randomly sampled accident would involve a teenager a percent of the time that falls inside the confidence interval limits. c) Explain what "95% confidence" means. About % of random samples of size (Type integers or decimals. Do not round.) will produce confidence intervals that contain(s) the of accidents involving teenagers.
