The article "Vehicle-Arrival Characteristics at Urban Uncontrolled Intersections" (V. Rengaraju and V. Rao, Journal of Transportation Engineering, 1995: 317-323) presents data on traffic characteristics at 10 intersections in Madras, India. One characteristic measured was the speeds of the vehicles traveling through the intersections. The accompanying table gives the 15th, 50th, and 85th percentiles of speed (in km/h) for two intersections. Percentile Intersection 15th 50th 85th 27.5 37.5 40.0 в 24.5 26.5 36.0 If a histogram for speeds of vehicles through intersection A were drawn, would it most likely be skewed to the left, skewed to the right, or approximately symmetric? Explain. b. If a histogram for speeds of vehicles through intersection B were drawn, would it most likely be skewed to the left, skewed to the right, or approximately symmetric? Explain. a.
