(b) in what gas mileage range does chebyshev's inequality predict that at least 75% of the selection will fall? (enter your answer using interval notation. round your answers to two decimal places.) , (c) what is the actual percentage of suv models of the sample that fall in the range predicted in part (b)? (round your answer to two decimal places.) % which gives the more accurate prediction of this percentage: chebyshev's rule or the empirical rule? chebyshev's rule empirical rule
