Answer 1

I wanna say that it's 0.002 correlation, and it's a common relationship...Is this a written part or are there answer choices?

Answer 2

Answer:

0.80 and strong and positive

Step-by-step explanation:

Using a graphing calculator, I graphed the scatter plot formed by the data.  It is attached.

Then I ran a linear regression; the r-value given (attached in a screenshot) was 0.82333371, which rounds to 0.80.

Since this r-value is positive and close to 1, this means there is a strong positive relationship between the variables.
