Chebyshevs rule and the empirical rule are useful as a check on the calculation of the standard

Question:

Chebyshev’s rule and the empirical rule are useful as a check on the calculation of the standard deviation. For example, suppose we calculated the standard deviation for the gas mileage data ( Table 2 ) to be 5.85. Are there any “clues” in the data that enable us to judge whether this number is reasonable?
