Math Problem Statement
Stoaches are fictional creatures, sometimes mistaken for mome raths.
Suppose a two-tailed t -test is conducted to test for a difference between the population means of adult female stoach weights and adult male stoach weights. The female sample has 12 weights, and the male sample has 23 weights. The t -statistic for the test is -0.38627. What is the p -value? (Give your answer to 4 decimal places.)
