Question

(3.36) NOTE: The numerical values in this problem have been modified for testing purposes. In its Fuel Economy Guide for 2014 model vehicles, the Environmental Protection Agency gives data on 1160 vehicles. There are a number of high outliers, mainly hybrid gas-electric vehicles. If we ignore the vehicles identified as outliers, however, the combined city and highway gas mileage of the other 1134 vehicles is approximately Normal with mean 22.7 miles per gallon (mpg) and standard deviation 5.3 mpg, How high must a 2014 vehicle's gas mileage( 0.01) be to fall in the top 10% of all vehicles? (Use software) Gas mileage mpg eBook (3.38) NOTE: The numerical values in this problem have been modified for testing purposes In its Fuel Economy Guide for 2014 model vehicles, the Environmental Protection Agency gives data on 1160 vehicles.

If we ignore the vehicles identified as outliers, however, the combined city and highway gas mileage of the other 1134 vehicles is approximately Normal with mean 22.8 miles per gallon (mpg) and standard deviation 5.2 mpg The quintiles of any distribution are the values with cumulative proportions 0.20, 0.40, 0.60, and 0.80. What are the quintiles of the distribution of gas mileage? (Use software) The first quintile is (0.01 mpg) The second quintile is (10.01 mpg) mpg. The third quintile is (±0.01 mpg) mpg. The fourth quintile is (0.01 mpg)mpg mpg
