If a molecule in a solid has a temperature of T=hf/2k, then the average energy of vibration is (3/2)kT.

According to the theory of Equipartition theory of energy, the average energy associated with each independent degree of freedom is (1/2)kT.

A solid is supposedly known to have 3 degrees of freedom.

Therefore, its average vibrational energy should be (3/2)kT.
