Question: A number of minor automobile accidents occur at various high-risk intersections in Teton County despite traffic lights. The Traffic Department claims that a modification in the type of light will reduce these accidents. The county commissioners have agreed to a proposed experiment. Eight intersections were chosen at random, and the lights at those intersections were modified. The number of minor accidents during a six-month period before and after modification were:
Number of Accidents
A B C D E F G H
Before modification 5 7 6 4 8 9 8 10
After modification 3 7 7 0 4 6 8 2
These samples are "paired" (really just one sample, two observations, right?)
Required:
At the .01 significance level is it reasonable to conclude that the modification reduced the number of traffic accidents? Show all steps.
