Answer 3

ooh i got confused
it says "not true" very tricky

Answer 4

so unfortunately your answer is not correct
3 out of 10 boys prefer to floss in the morning, and \(\frac{3}{10}=.3=30\%\) i.e. that IS true

Answer 5

3 boys floss in the morning and 4 girls do to. So that makes C right?

Answer 6

right C is the correct one

Answer 7

hold on a second, i think there is some confusion

Answer 8

More girls prefer to floss in the morning.
i take this to mean that more girls floss in the morning than floss at night, and that is NOT true

you took it to mean that more girls than boys floss in the morning and that IS true
i guess it is a matter of interpretation, but i would go with C as the only one of the statements that is NOT true

Answer 9

OK, I see. :)
