When the light turns yellow, should you stop or go through it? A 2011 article defines the "indecision zone" as the period when a vehicle is between 2.5 and 5.5 seconds away from a intersection. At the intersection of Route 7 and North Shrewsbury in Clarendon, Vermont, 150 vehicles were observed to encounter a yellow light in the indecision zone, and 21 of them ran the red light. At the intersection of Route 62 and Paine Turnpike in Berlin, Vermont, 175 vehicles entered the intersection in the indecision zone, and 20 ran the red light. Can you conclude that the proportion of red-light runners differs between the two intersections? (A) Yes (B) No
