3) [20 pts] Carbon monoxide (CO) emissions for cars vary with mean 2.9 gm/mi and standard deviation 0.4 gm/mi. The Ponaxtiruchiranalignim Car Rental Fleet has 10 of these cars in its fleet, acquired from various (i.e., random) sources. The CO emissions follow a normal distribution. a) What is the probability that a randomly selected car from the street has a CO emission greater than 3.1 gm/mi. b) What is the probability that a randomly selected car from the fleet has...

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?
