At a specified point on a highway, vehicles are known to arrive according to a Poisson process. Vehicles are counted in 20 second intervals, and vehicle counts are taken in 120 of these time intervals. It is noted that no cars arrive in 18 of these 120 intervals. Estimate the percentage of time headways that will be 10 seconds or greater and those that will be less than 6 seconds. O 0.873 O 0.387 O 0.738 O 0.837
