Automobile manufacturers are interested in the difference in reaction times for drivers reacting to traditional incandescent lights and to LED lights. A sample of 12 drivers are told to press a button as soon as they see a light flash in front of them and the reaction time was measured in milliseconds. Each driver was shown each type of light. A 99% confidence interval for the average difference between the two reaction times (traditional - LED) was (-30.83, 271.17). Which of the following is the appropriate conclusion? Question 5 options: 1) We are 99% confident that the average difference in reaction times for all drivers is negative, with the higher reaction time being with LED lighting. 2) We are 99% confident that the average difference in reaction times for all drivers is negative, with the higher reaction time being with traditional lighting. 3) We are 99% confident that the average difference in reaction times for all drivers is positive, with the higher reaction time being with LED lighting. 4) We are 99% confident that the average difference in reaction times for all drivers is positive, with the higher reaction time being with traditional lighting. 5) There is not a significant difference in the average reaction times for the two different types of lighting.

Automobile manufacturers are interested in the difference in reaction times for drivers reacting to traditional incandescent lights and to LED lights. A sample of 12 drivers are told to press a button as soon as they see a light flash in front of them and the reaction time was measured in milliseconds. Each driver was shown each type of light. A 99% confidence interval for the average difference between the two reaction times (traditional - LED) was (-30.83, 271.17). Which of the following is the appropriate conclusion?

Question 5 options:

1)	We are 99% confident that the average difference in reaction times for all drivers is negative, with the higher reaction time being with LED lighting.

2)	We are 99% confident that the average difference in reaction times for all drivers is negative, with the higher reaction time being with traditional lighting.

3)	We are 99% confident that the average difference in reaction times for all drivers is positive, with the higher reaction time being with LED lighting.

4)	We are 99% confident that the average difference in reaction times for all drivers is positive, with the higher reaction time being with traditional lighting.
