A sensitive piece of electronic equipment is interfered with by a 60Hz hum.

A manufacturer claims his simple circuit can effectively eliminate that noise. The manufacturer’s specification sheet does not show what components make up the design, but rather, lists the transfer function as

and claims it will reduce the interfering signal by at least 300 times, that is attenuate it by more than 50 dB without any noticeable attenuation of signals as near as 58 and 62 Hz (less than 0.5 dB).
Test the manufacturer’s assertion by calculating the sinusoidal steady-state output for five frequencies: 10, 58, 60, 62, and 100 Hz.
