Given this information, which of the following statements are true?

Answer 1

Don't you just hate it when they throw figures at you seemingly with the intent of confounding? :P

Answer 2

omg yes xD

Answer 3

Okay, let's set the records straight...
For starters, these percentages are percentages with respect to the entire student population.
Male AND Female.

Oh, and girls' haircuts cost a lot more in general, too, apparently.
tsk tsk
girls :/

But I digress...
Let's check each one at a time
A: 20% of all males spent from 16 to 31 dollars.

Just how true is this?

Answer 4

20/40?

Answer 5

Very good.
So the actual percentage of boys who had 16-31 dollar haircuts is...?

Answer 6

50?

Answer 7

Right...
..did you really need help with this?

Answer 8

yes because A is the easiest one lol bu B confuses me because what is the whole percent of all students

Answer 9

Like I said, all the percentages on the table are percentages with respect to ALL the students, which is why B should be the easiest.
It involves no calculation lol

So, check the percentage of students who are in fact, female, and spent more than 32 dollars for their haircut. Is it, in fact, 45%?
:P
