Question

1. To illustrate the effects of driving under the influence (DUI) of alcohol, a police officer brought a DUI simulator to a local high school. Student reaction time in an emergency was measured with unimpaired vision and also while wearing a pair of special goggles to simulate the effects of alcohol on vision. For a random sample of nine teenagers, the time (in seconds) required to bring the vehicle to a stop from a speed of 60 miles per hour was recorded.

	normal	impaired
1	4.47	5.78
2	4.34	5.65
3	4.48	5.71
4	4.67	5.21
5	4.39	5.88
6	4.72	5.43
7	4.65	5.35
8	5.98	5.53
9	4.75	5.59

Test the claim that there is a no difference in braking time with impaired vision and normal vision at the 0.05 level of significance

-Is there any way of solving this on stat crunch
