are sampled areas of a city. All intersections have approximately equal daily traffic. Ten of the intersections are controlled by yield signs, and ten are controlled by stop signs. The concentrations of CO (in parts per million) are given in the table below. Because the stop signs cause more cars to travel at lower speeds, encourage periods of engine idling, and create more acceleration-deceleration phases, it is hypothesized that intersections with stop signs will have higher CO concentrations. Is this hypothesis supported at a = 0.05?
