Answer 1

list is getting longer.... @marissalovescats is busy with AP calc

Answer 2

Satellite, I won the competition before, right? You still want to compete with *me* ?

Answer 3

no i will cut my losses

Answer 4

CCG: Pretty please, post your question RIGHT AWAY. Can't stand the suspense of wondering what you want to discuss.

Answer 5

This is going to be a long table again! :-)

Answer 6

...but nothing that mathslover couldn't handle.

Answer 7

Robinson asked a random sample of 50 classmates whether they had ever read a Shakespeare play. He also asked whether they had ever seen a professional production of a play. He recorded his data in the two-way table shown below.

Shakespeare No Shakespeare Total
Play 17 7 24
No Play 11 15 26
Total 28 22 50

Which two-way relative-frequency table best reflects Robinson’s data?

A. Shakespeare No Shakespeare
Play 34% 14%
No Play 66% 86%


B. Shakespeare No Shakespeare
Play 66% 14%
No Play 34% 86%


C. Shakespeare No Shakespeare
Play 61% 32%
No Play 39% 68%


D. Shakespeare No Shakespeare
Play 68% 39%
No Play 32% 61%

Answer 8

C

Answer 9

Whoa! How so C? I'm much more interested in knowing your criteria for accepting or rejecting the alternative answers, along with WHY you accepted or rejected it/them.

Answer 10

Last time I got picky about the content of the table headers. That was one of my criteria for acceptance or rejection. Another critierion was whether all the summations in those tables was correct or not.

So, what are your criteria for the current problem?

Answer 11

I did this one here

Answer 12

\(\frac{17}{28}=60.71\%\) which i guess we can round to \(61\%\) so that part is right

Answer 13

I know it's either C or D, I thought it was C though...

Answer 14

and \(\frac{7}{22}\) is close to \(32\%\) so that is correct also

Answer 15

can't be D
C is the only one with \(61\%\) in it

Answer 16

Again, i'd like to suggest that you be really clear about your criteria, so that you can justify your answers. I like Satellite's statement, "C is the only one with 61% in it," because he explains his criterion in that regard and, I'd suppose, rejects the alternatives that do not include 61%.

Answer 17

So I'm right? You giys got me a little confused now.

Answer 18

yes dear you are right

Answer 19

CC: It'd make my day if you'd develop the skills you need to decide for yourself whether you're right or not. That's why I keep prodding you to name your criteria!

Answer 20

I don't at all mean to be unkind, but I believe that at this level it becomes increasingly important to be able to justify what you're doing so that you don't need to rely on others to tell you whether you're "right" or not.

Answer 21

I'm pretty sure I'm right on most of them. I don't really wanna take any chances since these are study guides. I wanna make sure if I get one wrong, then I do know how to do it. I have to know this, because even though school is already out for me. I still have one BIG math test left. :(

Answer 22

I appreciate your wanting so badly to do well. If you "have to know this," having a systematic plan of attack (which for me means developing criteria for judging the correctness of my approaches and answers) could be very, very helpful.
