Survey for Math

Hey guys, like Mahina, I have a math project to do.

My question is whether there is a correlation between gender and genre of book bought.

Please answer the following:

1) Gender (should be easy)
2) Age (don't tell me your actual age. Just, are you under 20, 21-30, 31-40 and so on.)
3) If you were to buy a book right at this moment, what Genre would it be? (try to answer this as truthful as you can, or if you did buy a book lately, what genre was it?)
