Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
What is the average relative permeability with a resistivity smaller than 1.12 and a surface resistance relative to copper smaller than 1?

### Inputs:
table_name: table, columns: ['Material', 'Resistivity (10 −6 ohm-inches)', 'Relative permeability', 'Skin depth, inches', 'Surface resistance, Relative to copper']

### Response:
SELECT AVG Relative permeability FROM table WHERE Resistivity (10 −6 ohm-inches) < 1.12 AND Surface resistance, Relative to copper < 1
