The level of nitrogen oxides (NOX) and nonmethane organic gas (NMOG) in the exhaust over the useful life (150,000 miles of driving) of cars of a particular model varies Normally with mean 90 mg/mi and standard deviation 4 mg/mi. A company has 25 cars of this model in its fleet. @ Macmillan Learning Using Table A, find the level L such that the probability that the average NOX + NMOG level x for the fleet is greater than L is only 0.03. Give your answer to three decimal places. 83.081 L = Incorrect
