Carbon monoxide emissions for a particular car vary with an average of 2.5 g/mi and a standard deviation of 0.3 g/mi. A company has 60 of these cars in its fleet. If X= the CO level for the company's fleet, what is the probability that the average of the 60 cars will be within 0.05 g/mi of the population mean? Round your answer to four decimal places.

The level of nitrogen oxides (NOX) in the exhaust of cars of a particular model is normally distributed with mean 0.2 grams per mile (g/mi) and standard deviation of 0.05 g/mi. If the government regulations call for NOX emissions no higher than 0.3 g/mi, what is the probability that a single car of this model meets the NOX requirement?
