Say that you conduct a study of 1,000 people and measure the mean wait time (in hours) to get through security at a major airport. You find a 99% confidence interval of (0.7, 2.1). Which of the following statements are correct? (select all that apply)

99% of passengers can expect to wait between 0.7 hours and 2.1 hours

You found just one sample result. However, if you calculated a 99% confidence interval for each and every possible sample, 99% of them would contain the true mean.

There is a 99% chance the true mean wait time is between 0.7 hours and 2.1 hours.

There is a .99 probability the true mean wait time is between 0.7 hours and 2.1 hours.

You found just one sample result. However, if you calculated a mean for each and every possible sample, 99% of the means would fall between 0.7 hours and 2.1 hours.

We are 99% confident that the true mean wait time is between 0.7 hours and 2.1 hours.
