An old myth claims that boys are better at math than girls. A high school guidance counselor collects the math grades from a random sample of 50 boys and another random sample of 50 girls. The guidance counselor then tested the hypothesis against the one-tail alternative and found P = 0.35.Which is true?

▸ None of these.

▸ There's a 35% chance that there’’s really no difference in math grades.

▸ The boys' grades are 35% higher than the girls' grades.

▸ There's a 35% chance that boys have higher math grades than girls.
