From the given data, we can see that the mean for the male sample is 7.6 miles and the mean for the female sample is 5.8 miles. Hence, on average, males commute farther than females. Therefore, option C is the correct answer. Option A cannot be concluded as the range does not give a complete picture of the variability. Option B and D are also incorrect as they are contradicted by the mean values.
