Suppose the following are gas mileages (in miles per gallon) of a selection of large and midsized sport utility veri 25, 25, 23, 22, 38, 25, 20, 19, 22, 22, 19, 16, 17, 18, 18, 15 (a) Find the sample standard deviation (rounded to two decimal places). 5.44 Nice work. (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.) 18.72,40.48 X (c) What is the actual percentage of SUV models of the sample that fall in the range predicted in part (b)? 93.75 % Which gives the more accurate prediction of this percentage: Chebyshev's rule or the empirical rule? O Chebyshev's rule O empirical rule
