17)The level of nitrogen oxides (NOX) and nonmethane organic gas (NMOG) in the exhaust over the useful life (150,000miles150,000miles of driving) of cars of a particular model varies Normally with mean 80mg/mi80mg/mi and standard deviation 6mg/mi.6mg/mi. A company has 1616 cars of this model in itsfleet.

Using TableA, find the level L such that the probability that the average NOX+NMOGNOX+NMOG level x for the fleet is greater than L is only0.03.only0.03.

Give your answer to three decimalplaces.
