Confidence interval is given by (0.161, 39). Which of the following is a correct interpretation of the 95% confidence level? 95 percent of all random samples of 400 drivers chosen from the population will have sample proportions between 0.161 and 0.239. 95 percent of all random samples of 400 drivers will produce confidence intervals which contain the true proportion of all drivers who never use their cruise control. We are 95 percent confident that the true proportion of all drivers who never use their cruise control is between 0.161 and 0.239. There is a 0.95 probability that the true proportion of all drivers who never use their cruise control is between 0.161 and 0.239. 95 percent of all random samples of 400 drivers chosen from the population will produce confidence intervals which contain 0.20.

A 2015 survey of 400 randomly selected drivers reported that 20 percent of the drivers who were surveyed never use their cruise control. A 95% confidence interval is given by (0.161, 0.239). Which of the following is a correct interpretation of the 95% confidence level? 95 percent of all random samples of 400 drivers chosen from the population will have sample proportions between 0.161 and 0.239. 95 percent of all random samples of 400 drivers will produce confidence intervals which contain the true proportion of all drivers who never use their cruise control.
