###### In 2017, the entire fleet of light?duty vehicles sold in theUnited States by each manufacturer must emit an average of no morethan 90 milligrams per mile (mg/mi) of nitrogen oxides(NOX) and nonmethane organic gas (NMOG) over the useful life(150,000 miles of driving) of the vehicle.NOX + NMOG emissions over the useful life for one carmodel vary Normally with mean 84 mg/mi and standarddeviation 6 mg/mi.(a) What is the probability that a single car of this modelemits more than 90 mg/mi of NOX + NMO

In 2017, the entire fleet of light?duty vehicles sold in the United States by each manufacturer must emit an average of no more than 90 milligrams per mile (mg/mi) of nitrogen oxides (NOX) and nonmethane organic gas (NMOG) over the useful life (150,000 miles of driving) of the vehicle. NOX + NMOG emissions over the useful life for one car model vary Normally with mean 84 mg/mi and standard deviation 6 mg/mi. (a) What is the probability that a single car of this model emits more than 90 mg/mi of NOX + NMOG? (Enter your answer rounded to four decimal places.) probability: (b) A company has 16 cars of this model in its fleet. What is the probability that the average NOX + NMOG level ????¯ of these cars is above 90 mg/mi? (Enter your answer rounded to four decimal places.) probability: #### Similar Solved Questions
