Answer
62 Hz to 20000 Hz
Explanation
This question is asking for the common auditory frequency range between humans and dogs. Humans can hear frequencies ranging from 20 Hz to 20000 Hz, while dogs can hear from 62 Hz to 45000 Hz. The common frequencies are those which fall into both ranges. Looking at the data, the common range is from 62 Hz to 20000 Hz- any frequency less than 62 Hz would be undetectable by dogs, and any frequency more than 20000 Hz would be undetectable by humans. Hence, we choose the higher of the two lower bounds (62 Hz) and the smaller of the two upper bounds (20000 Hz) as the range in question.
