Table schema:
CREATE TABLE table_name_67 (amerindian__both_hispanic_and_non_hispanic_ INTEGER, black__both_hispanic_and_non_hispanic_ VARCHAR, white__both_hispanic_and_non_hispanic_ VARCHAR)

Question: What is the highest Amerindian (Hispanic/Non-Hispanic) value having a Black (Hispanic/Non-Hispanic) of 15.7 and White (Hispanic/Non-Hispanic) over 69.5?
SQL: SELECT MAX(amerindian__both_hispanic_and_non_hispanic_) FROM table_name_67 WHERE black__both_hispanic_and_non_hispanic_ = 15.7 AND white__both_hispanic_and_non_hispanic_ > 69.5
