CREATE TABLE table_name_42 (level NUMBER, example_name VARCHAR2, number_of_hus__approximate_ VARCHAR2)

What is the mean level number when the example name is lower snake and the approximate number is hus is less than 370?
SELECT AVG(level) FROM table_name_42 WHERE example_name = "lower snake" AND number_of_hus__approximate_ < 370
SELECT AVG("level") FROM "table_name_42" WHERE "example_name" = "lower snake" AND "number_of_hus__approximate_" < 370
