CREATE TABLE table_41896 ("Name" CLOB, "Level" FLOAT, "Digits" FLOAT, "Average size  ( square miles ) " CLOB, "Number of HUs  ( approximate ) " FLOAT, "Example name" CLOB, "Example code  ( HUC ) " FLOAT)

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_41896 WHERE "Example name" = 'lower snake' AND "Number of HUs (approximate)" < '370'
SELECT AVG("Level") FROM "table_41896" WHERE "Example name" = 'lower snake' AND "Number of HUs (approximate)" < '370'
