Answer 6

It's unfortunate that the tables don't retain their formatting very well!

Answer 7

kk i understand what you are saying hold up :D

Answer 8

I think this is A...

Answer 9

A

Answer 10

That's much easier to read, thanks!

I don't agree with A, however. Shouldn't the number be the # of rows where the kids are 16 and over (45) divided by the row total (82) = 55%?

Answer 11

I'm not sure how you are getting the other percentage.

Answer 12

it has the highest score out of all the other numbers in the columns/rows. It's 45 vs. 20, 26, 12, 17

Answer 13

no wait lol...
i did:
45/57 = 78.9...typos sorry...

Answer 14

I don't think you're in need of my assistance anymore:D

Answer 15

lol so its A right?

Answer 16

Yes

Answer 17

can u guys help me with a few more? maybe like 2?

Answer 18

No, I still think B. 45 out 82 families with kids all over 16 choose to go out of state. that's 55%

17/82 = 20 percent went camping
20/82 = 24 percent stayed local

Answer 19

Yeah, sure.
You know what, just ask Palmer, he/she's probably right

Answer 20

kk... miss jade...

Answer 21

I think this is C marginal...

Answer 22

the totals for rows and columns are the marginal ones, the body of the table has the relative ones

Answer 23

meaning this is B?

Answer 24

sorry, thinking faster than I type :-) the body has the joint frequencies, and these are relative because they are not counts

Answer 25

*tilts head* what does that mean?

Answer 26

Well, if we have a table that looks like this
tennis football total
boys 10 30 40
girls 30 0 30
total 40 30 70

That's a table of counts, right? 10 boys prefer tennis, 30 prefer football, 40 boys in all. all 30 girls prefer tennis, none prefer football, 30 girls in all. etc.

Now, if instead we had a table showing

tennis football total
boys 0.25 0.75 1.0
girls 1.0 0.0 1.0
totals 1.25 0.75 2.0

that's a relative table, because each entry is the fraction of the whole

Answer 27

Oh ok i undeadstand...

Answer 28

I guess my numbers ought to be cut roughly in half so that the two total columns go to 1.0
tennis football total
boys 0.14 0.43 0.57
girls 0.43 0 0.43
total 0.57 0.43 1.0

Answer 29

so girls who prefer tennis are 0.43 of the group, etc.

Answer 30

So its marginal relative frequency?

Answer 31

no, our sample is from the middle of the table, is it not?

Answer 32

yeah, female students who prefer dancing. that's from the body, and it's not a count, so it should be a joint relative frequency, or you get a full refund on everything you've paid me :-)

Answer 33

o.o so its A.
ok i think i partially undeadstand..

Answer 34

Cheers Palmer!*holds up apple cider bottle*
