CREATE TABLE table_13353 ("Parameter" TEXT, "Symbol" TEXT, "Best fit  ( WMAP only ) " TEXT, "Best fit  ( WMAP ,  extra parameter ) " TEXT, "Best fit  ( all data ) " TEXT)

What is the parameter when the best fit (WMAP only) is .9 .1, and a best fit (WMAP, extra parameter) is .92 .12?
SELECT "Parameter" FROM table_13353 WHERE "Best fit (WMAP only)" = '.9 ± .1' AND "Best fit (WMAP, extra parameter)" = '.92 ± .12'
SELECT "Parameter" FROM "table_13353" WHERE "Best fit (WMAP only)" = '.9 ± .1' AND "Best fit (WMAP, extra parameter)" = '.92 ± .12'
