A researcher studying reaction time of drivers states that, “A 95% confidence interval for the mean time it takes for a driver to apply the brakes after seeing the brake lights on a vehicle in front of him is 1.2 to 1.8 seconds.” Which of the following statements correctly interprets this confidence interval? We are 95% confident that the interval from 1.2 to 1.8 seconds captures the true mean amount of time it takes for drivers to apply the brakes after seeing the brake lights on a vehicle in front of him.

We are 95% confident that the interval from 1.2 to 1.8 seconds captures the true proportion of time it takes for drivers to apply the brakes after seeing the brake lights on a vehicle in front of him.

95% of drivers will apply the brakes 1.2 to 1.8 seconds after seeing the brake lights on a vehicle in front of him.

95% of the drivers in the sample applied the brakes 1.2 to 1.8 seconds after seeing the brake lights on a vehicle in front of him.

Approximately 95% of the time a driver will apply the brakes 1.2 to 1.8 seconds after seeing the brake lights on a vehicle in front of him.
