Carbon monoxide​ (CO) emissions for a certain kind of car vary with mean 3.143​g/mi and standard deviation 0.6​g/mi. A company has60 of these cars in its fleet. Let y represent the mean CO level for the​ company's fleet.

​a) What's the mean and the standard deviation

​b) Estimate the probability that y is between 3.2 and 3.3 ​g/mi.

​c) There is only a 10​% chance that the​ fleet's mean CO level is greater than what​ value?

Compare the carbon monoxide (CO) emissions expected from two different automotive engines. At a standard testing condition, Engine A consumes octane (C8H18) at a rate of 80 g/min along with 1475 liters per minute (L/min) of air (at P=0.8 atm, T=330 K). Engine B consumes 35% more fuel and 20% more air at the same standard test condition. a. How would you expect the engines' carbon monoxide emissions to compare at the standard test condition? b. How would your answers...
