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 CO emissions in excess of 3.1 gm/mi.
c) What is the shape of the distribution of the CO emissions of the cars in the fleet?
d) Construct the normal curve for the cars in the fleet.
e) What are the conditions for the Central Limit
