Carbon monoxide (CO) emissions for a certain kind of car vary with mean 3.706 g/mi and standard deviation 0.6 g/mi. A company has 70 of these cars in its fleet. Let y overbar represent the mean CO level for the company's fleet. a) What's the approximate model for the distribution of y overbar? Explain. b) Estimate the probability that y overbar is between 3.8 and 3.9 g/mi. c) There is only a 5% chance that the fleet's mean CO level is greater than what value?

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.
