Carbon monoxide emissions for a certain kind of car vary with a mean u=2.3 g/mi. and a standard deviation o=0.7 g/mi. A company has 60 of these cars in their fleet. Let y represent the mean CO level for the Company fleet.
Estimate the probability the y is between 2.4 and 2.5 g/mi.
P(2.4< Y <2.5)=
Note: "There is supposed to be a _ over the Y"
This solution shows all the steps to solve the given probability problem.
