Question

Who wants a medal!?
Help with scatter plots, please?

Answer 1

The table below shows the lengths and weights of six dolphins at an aquarium. Use the data from Pax and Snowflake to create a linear model that predicts the weight (y) of a dolphin given its length (x). Which dolphin’s weight differs most from the value predicted by this model?

Blaze
JoJo
Corky
Shadow

Answer 2

Here's the graph for the information in the chart:

Answer 3

Are you talking about weight to length ratio

Answer 4

Um, I think so.

Answer 5

If that is the case then Shadow is the one which differs the most.

Answer 6

Although I don't fully know what it wants so I could be wrong.

Answer 7

That's the answer I chose last time, and it told me that I was incorrect.
I am so confused. D:
Maybe you could help with another question I have?

Answer 8

Ok

Answer 9

Aaliyah, Julio, Dan, and Miriam are each studying sets of data. Aaliyah is working with 14 data pairs with a correlation coefficient of 0.9. Julio is working with 13 data pairs with a correlation coefficient of –0.8. Dan is working with 10 data pairs with a correlation coefficient of 0.1. Miriam is working with 15 data pairs with a correlation coefficient of –0.2. For which two data sets is a linear regression model reasonable?

Aaliyah’s and Julio’s data sets
Julio’s and Miriam’s data sets
Dan’s and Miriam’s data sets
Miriam’s and Aaliyah’s data sets

Answer 10

Well what do you think.

Answer 11

It is a bit strange how we keep getting the wrong answers.

Answer 12

It is odd. I think I'm going to email my teacher after my retake, especially if I get them wrong this time.

Answer 13

On this one, I honestly have no idea.

Answer 14

Yes. I honestly can't help you with this one.

Answer 15

Well thank you anyways. ^_^

Answer 16

I really don't like word questions. I find it confusing at times.

Answer 17

I am the same way with word problems, especially when you have to make an equation out of the words.

Answer 18

What did you think it is? I don't mind making an effort to help you.

Answer 19

Yes. I totally agree.

Answer 20

I guessed the first one since they were the closest correlations. I don't know.

Answer 21

Yea. I don't know either. I don't want to give you a wrong answer. Is this a timed test?

Answer 22

Let me try.

Answer 23

I am thinking of what to do.

Answer 24

I know that the closer to 1 or -1 the stronger the correlation

Answer 25

if it is near 0 then the correlation is not predictable.

Answer 26

I would go with the second one

Answer 27

Wow. I just now realized that my reply never sent. O.o (stupid internet connection):
"Well I got an 80 on this one, so I'm satisfied with it.
And apparently Corky isn't the right dolphin either, but I did find out that the first answer, "Aaliyah’s and Julio’s data sets", was correct.
Thank you for trying to help though. I really do appreciated it. :)
