Question: What is the sum of skin depth with a resistivity of 1.12 and a relative permeability larger than 1?
Columns: ['Material', 'Resistivity (10 −6 ohm-inches)', 'Relative permeability', 'Skin depth, inches', 'Surface resistance, Relative to copper']
Types: ['text', 'real', 'real', 'real', 'real']
Sample row: ['Carbon steel 1010', 9.0, 200.0, 0.004, 56.25]
SQL:

assistant: SELECT SUM("Skin depth, inches") FROM "Table" WHERE "Resistivity (10 −6 ohm-inches)" = 1.12 AND "Relative permeability" > 1.0;
