Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_68993 ( "Material" text, "Resistivity (10 \u22126 ohm-inches)" real, "Relative permeability" real, "Skin depth, inches" real, "Surface resistance, Relative to copper" real )

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

### Accurate SQL ###

SELECT AVG("Relative permeability") FROM table_68993 WHERE "Resistivity (10 \u22126 ohm-inches)" < '1.12' AND "Surface resistance, Relative to copper" < '1'
