Suppose the mileages of the cars in a randomly selected parking lot follow the normal distribution. 1,000 cars in the parking lot are surveyed and the average or mean mileage is 30,000 on those cars. If the standard deviation is 5,000, how many cars would fall in the range of mileage of 25,000 to 35,000 approximately? (use 68% for the 1 SD coverage and 96% for 2 SD)
