Suppose a radar device tracks the speeds of cars traveling through a city intersection. After record

Suppose a radar device tracks the speeds of cars traveling through a city intersection. After recording the speeds of over 10,000 different cars, local police determine that the speeds of cars through this intersection, in kilometers per hour, follow a normal distribution with a mean u 45 and standard deviation o 5. The area under the normal curve between 40 and 50 is equal to 0.68 Select all of the correct interpretations regarding the area under the normal curve. In any sample of cars from this city intersection, 68% travel between 40 and 50 km/h In the long run, 68% of cars passing through this city intersection travel either 40 or 50 km/h. The probability that a randomly selected car is traveling between 40 and 50 km/h is equal to 0.68 The proportion of cars traveling faster than 40 km/h is equal to 0.68 The long-run proportion of all cars traveling between 40 and 50 km/h is equal to 0.68.
